test(terminal): keep the argv test child alive through its assertion

The POSIX argv test reads the terminal screen while its child can exit and dispose the parser. Keep the child alive until the assertion completes, as other screen tests do, and let the existing session cleanup terminate it.

+## OpenCode with an existing v2 server
+
+Paseo first uses an explicitly configured server, then a healthy locally registered OpenCode v2 service, then starts its own helper. It never stops a reused service. To select a server explicitly, set its URL in the provider environment:
+
+```json
+{
+  "agents": {
+    "providers": {
+      "opencode": {
+        "env": {
+          "PASEO_OPENCODE_SERVER_URL": "http://127.0.0.1:4096",
+          "PASEO_OPENCODE_SERVER_PASSWORD": "<server password>"
+        }
+      }
+    }
+  }
+}
+```
+
+`PASEO_OPENCODE_SERVER_URL` must be an absolute `http` or `https` URL. Omit `PASEO_OPENCODE_SERVER_PASSWORD` when the server has no authentication; when set, Paseo authenticates with HTTP Basic auth as `opencode`.
+
+A configured URL takes precedence even when unreachable; Paseo reports the connection error. The local service registration supplies its own authentication. For a discovered local service, Paseo installs its bridge package in OpenCode's watched global plugin directory without changing the existing configuration. Refresh reads the existing service's catalogs without starting another server.
+
+An explicitly configured server needs the bridge installed separately. Connect once and start a session: the setup error gives the local package directory. Copy that directory to the server's OpenCode global `plugins` directory, then retry. For a server on another machine, set `PASEO_OPENCODE_BRIDGE_PORT` in the Paseo OpenCode provider environment before starting Paseo, and set `PASEO_OPENCODE_BRIDGE_URL` to the URL the OpenCode server can use to reach that port. For example, an SSH reverse tunnel can expose the Paseo loopback port on the OpenCode host. The bridge token is exchanged through the OpenCode connection and is not written into the plugin package.
+
+OpenCode's custom MCP registrations are shared by all sessions in a location. Paseo rejects custom MCP servers and per-agent process environment overrides on a reused server rather than applying them to other sessions or ignoring them. Session identity is applied to each session's shell environment. A Paseo-owned helper supports custom process and MCP settings; it is selected when there is no explicit URL or healthy registered service.

 ## Z.AI (Zhipu) coding plan
 
 [Z.AI](https://z.ai) is a Chinese AI company (Zhipu AI) that offers an Anthropic-compatible API endpoint. Their GLM Coding Plan provides flat-rate access to GLM models through Claude Code's Anthropic API protocol. These are **not** Anthropic Claude models — they are Zhipu's own GLM models exposed through an Anthropic-compatible API.

 Pi RPC extension UI dialog requests (`select`, `input`, `editor`, `confirm`) are bridged into Paseo question permissions and answered with `extension_ui_response`. Pi extensions such as `ask_user` may chain dialogs: for example, a `select` can be followed by an optional-comment `input`. When an `ask_user` tool call declares `allowComment: true`, Paseo presents the selection and optional comment as one question permission, answers Pi's initial `select` immediately, then auto-answers the follow-up optional `input` with the comment the user already supplied (or an empty string). Preserve placeholders and optional/skip semantics for standalone optional inputs so the app can still distinguish "skip this optional input" from "cancel the whole dialog." Fire-and-forget extension UI requests such as notifications are intentionally ignored by the provider adapter unless Paseo grows first-class UI for them.
 
-OpenCode adapters target v1.14.46 and v2.0.10. V2 rejects binaries older than the tested 2.0.10 SDK at runtime selection. Runtime selection uses the configured command and environment.

 Use OpenCode v2 execution events to trigger turn completion, with active-state and durable-log reconciliation after admission, reconnect, and while a turn remains active. Do not use `session.wait`: a healthy turn exceeding Node's HTTP headers deadline produces a transport error while OpenCode keeps working. The live event feed has no replay, and shutdown interruption preserves the previous idle outcome, so the session snapshot alone cannot recover missed execution events. Quiet streams are healthy: v2 heartbeats are SSE comments, not application events.

Reload, idle runtime collection and daemon restart resume whatever handle the agent stored; a stored agent without one starts a new session instead. When there is no handle, `AgentManager` stores `getRuntimeInfo().sessionId` as one, so that ID follows the same rule. Codex, for example, starts a thread when the agent is created but writes its rollout only at its first turn, and `thread/resume` fails for it until then, so its adapter reports neither ID before Codex announces that turn.

 `setMode` and `setThinkingOption` may return an `AgentProviderNotice` when the provider knows the change needs user-facing context. For example, providers that stage changes until the next turn should return an `info` notice while a turn is already running. The app renders the notice generically as a toast; provider-specific lifecycle behavior stays in the provider implementation.

 xterm decides which column every cell occupies. The native views never let text advance move a cell. Each row is shaped once, one run per font face, so Hangul jamo, ligatures, combining marks, conjuncts and fallback fonts see their neighbours. Each shaped cluster is then drawn at its first cell's column, centred in the columns it owns, and scaled down when its glyphs are wider. Cursor, selection, hit-testing and copy all use xterm's columns, so they stay correct whatever the font does.
 
-A cluster is the run of cells the shaper merged, and it is drawn once from the shaped row. Drawing part of a cluster on its own reshapes it: a half-form conjunct such as `स्ते` comes apart into `स्` with a visible virama. So colour and selection never split a cluster. A cluster whose cells differ in colour is drawn once per colour, clipped to that colour's columns.
+A cluster is the run of cells the shaper merged, and it is drawn once from the shaped row. xterm usually keeps a conjunct in one cell (see [Character widths](#character-widths)), but a colour change inside it leaves `क्` and `ष` in separate cells that still shape together. Drawing part of a cluster on its own reshapes it: the conjunct comes apart into `क्` with a visible virama. So colour and selection never split a cluster. A cluster whose cells differ in colour is drawn once per colour, clipped to that colour's columns.
 
-Android also groups cells with `android.icu.text.BreakIterator`, because Minikin's advances and cursor boundaries alone split some conjuncts. Grapheme rules follow the OS ICU version. Android 10 (API 29) splits `स्ते` after the virama and renders it incorrectly. The tested corpus passed on API 33, 34 and 35; API 30–32 have not been tested. We accept that version-dependent limitation to avoid bundling approximately 14 MB of ICU4J data. CoreText keeps this conjunct together on iOS. This renderer does not guarantee identical shaping across OS versions.
+Android also groups cells with `android.icu.text.BreakIterator`, because Minikin's advances and cursor boundaries alone split some clusters that span cells. Grouping only merges whole cells, so a conjunct xterm keeps in one cell cannot be split by the OS. Grapheme rules follow the OS ICU version, and we accept that to avoid bundling approximately 14 MB of ICU4J data. Before the buffers used grapheme widths, Android 10 (API 29) split `स्ते` across its two cells. This renderer does not guarantee identical shaping across OS versions.
 
 `TerminalRowLayoutTest.kt` is the Android regression test. It draws the rows of `grapheme-rows.json` and compares each with its grapheme clusters drawn one at a time, and with a wrong clustering that must not match. `terminal-frame.test.ts` checks that those rows are what xterm produces and that the clusters are UAX #29 grapheme clusters. Run it with `./gradlew :paseo-terminal:connectedDebugAndroidTest` from `packages/app/android`, with `ANDROID_SERIAL` set.
 
 The view reports ready only after it has measured its grid size. The pane attaches with that size, so the daemon replays the terminal at the client's size. Before this, the replay arrived at the PTY's old size, the resize came after it, and the shell's redraw landed on the wrong rows.
 
-Emoji widths come from the headless buffer, which uses xterm's default Unicode 6 table. `👍` gets one column, and `👋🏽` and `🇰🇷` get two cells drawn as one cluster. Web loads the Unicode 11 addon, so the same output can wrap differently on web and native.
+## Character widths
+
+The daemon, native and web buffers all load `@xterm/addon-unicode-graphemes`: the daemon through `packages/server/src/terminal/headless-terminal.ts`, native in `createNativeHeadlessTerminal`, web in `terminal-emulator-runtime.ts`. Each emoji cluster takes one two-column cell, including VS16 (`❤️`), skin tones (`👋🏽`), flags (`🇰🇷`) and ZWJ sequences (`👨‍👩‍👧`). That is the width colour-emoji fonts draw at. Under xterm's default Unicode 6 table `😀` got one column, and the native views scaled it to half size to fit.
+
+Every buffer must use the same table. The daemon answers cursor-position reports (`CSI 6n`) from its buffer, and a client re-parses the daemon's ANSI replay with its own table. A disagreement moves the cursor and the later cells of any row that holds a disputed cluster: after replay from a Unicode 6 daemon, the cursor that followed `A😀😀😀B` lands inside the third emoji.
+
+Daemons that use grapheme widths advertise `server_info.features["terminal-grapheme-widths"]`. `terminal-pane.tsx` reads it once and passes `characterWidths` to the emulator. Against an older daemon the app keeps each renderer's previous table: xterm's default on native, Unicode 11 on web. An older app against a newer daemon cannot match it, because every client shares the daemon's one buffer. A terminal kept by a worker from an unreleased pre-grapheme build keeps that worker's table until it exits.
+
+The table follows Unicode grapheme clusters, as Node's `string-width` does for Ink-based agent TUIs. Indic conjuncts follow the same rule: `क्ष` and `स्ते` take one column, and the native views scale them down to fit it. Shells measure with the C library's `wcwidth` instead. glibc counts `❤️` as one column, `👋🏽` as four and `क्ष` as two, so a line editor that measures those disagrees with the terminal.
+
+Use `@xterm/addon-unicode-graphemes` 0.5.0-beta.330 or later. Earlier versions read their width table from the wrong offset when Node decodes it into a pooled `Buffer`, which gives wrong widths or a load error depending on earlier allocations. `headless-terminal.test.ts` forces that case in a fresh process.
