Add Antigravity CLI to ACP catalog

* Run Pi through its RPC interface

Replace the embedded Pi runtime packages with a process-backed runtime that starts pi --mode rpc, keeps the runtime port thin, and leaves provider behavior in the Paseo session and mapper modules.

Add focused adapter and mapper tests plus real Pi E2E coverage for the installed binary path.

* Keep Pi provider code in one module

* Add Pi session imports

* Enable Paseo MCP tools in Pi agents

Route injected MCP servers through Pi's MCP adapter and make structured MCP results visible to model-only clients.

Normalize Pi MCP proxy calls so Paseo timelines show the underlying tool names.

* Fix Pi import symlink tests on Windows

Create directory links explicitly in symlink cwd fixtures so Windows server tests exercise the intended path-equivalence behavior.

* Use native realpath for import cwd matching

Resolve import cwd matchers with native realpath so Windows symlink and junction sessions compare against the same path shape used by persisted provider data.

* Fallback realpath for Windows import matching

Use plain realpath when native realpath cannot resolve a cwd so symlink-equivalent persisted sessions still match on Windows runners.

* Add daemon system prompt support for Pi

* Fix Windows realpath import matching

* Remove Pi RPC migration plan doc

+after a few minutes, which is too long for a foreground app.
+
+`setupDarwinCompositorWatchdog`

+this. It polls the renderer for frame production every couple of seconds and,
+after a sustained stall while the window is visible and unlocked, restarts the
+GPU process so Chromium rebuilds the display link. The probe is skipped while
+the screen is locked or the window is hidden or minimized, since a window
+legitimately stops producing frames then.

+
+Pi is a process-backed provider. Paseo requires the user to have the `pi` binary installed and talks to it through `pi --mode rpc`; the server package does not embed Pi's SDK/runtime packages.
+
+Paseo's per-agent and daemon-wide system prompts are passed to Pi with `--append-system-prompt`, so Pi keeps its default coding prompt while receiving Paseo's additional instructions.
+
+Pi MCP support depends on the open-source `pi-mcp-adapter` extension being loaded for the agent cwd. Probe with Pi RPC `get_commands`; the adapter registers an extension command named `mcp` (often with `sourceInfo.source` containing `pi-mcp-adapter`). When Paseo injects MCP servers into Pi, write a per-agent MCP config and pass it with `--mcp-config` instead of modifying user or project MCP files. For local HTTP servers such as Paseo's own `/mcp/agents` endpoint, explicitly disable adapter OAuth (`auth: false`, `oauth: false`) in the generated config.
+
+Pi import discovery reads Pi's persisted JSONL session files because Pi RPC does not expose a recent-session listing command. Resume and full history hydration still go through `pi --mode rpc` using the session file as `nativeHandle`.
 
 Draft metadata lookups should avoid creating provider sessions when the upstream provider has top-level APIs for that metadata. Prefer `AgentClient.listModels`, `listModes`, `listCommands`, or `listFeatures` over creating a scratch `AgentSession`; scratch sessions can show up as empty native sessions in provider import/history UIs.
