Remove the "agent can be a terminal" branching from the entire codebase.
An agent is now always a session-backed chat agent. Standalone terminal
infrastructure (terminal component, ANSI handling, terminal-stream-protocol)
is preserved.
Server: delete ManagedTerminalAgent, AgentKind, TerminalExitDetails,
launchTerminalAgent, registerTerminalAgent, handleTerminalAgentExited,
supportsTerminalMode capability, buildTerminalCreate/ResumeCommand from
all providers, terminal agent persistence/projections.
App: delete terminal-agent-panel.tsx, terminal-agent-reopen-store.ts,
terminal/terminalExit fields on agent state, "Terminal Agents" launcher
section, terminal-agent workspace setup flow, terminal badge in agent list.
CLI: remove terminal column from ls, terminal-agent error from send.

Replace lucide file icons with colored SVGs from material-icon-theme covering
53 language/filetype-specific icons. Add chevron expand indicators for
directories, indent guide lines, rounded rows, and restyle the header toolbar
to match the git diff pane pattern.
Rewrite Getting Started in README and website docs to explain the
daemon, put agent CLI prerequisites first, and split setup into
Desktop App (recommended, bundles daemon) and CLI/headless paths.
Add "Components at a glance" section to ARCHITECTURE.md.
Replace three competing event paths (foreground stream, live event pump,
JSONL history poller) with a single push-based subscribe() + startTurn()
contract. This fixes duplicate user messages and stuck running state caused
by timing-based routing between concurrent event sources.
Key changes:
- AgentSession interface: remove stream(), add subscribe() and startTurn()
- All providers (Claude, Codex, OpenCode): single subscribers Set with
notifySubscribers() for push-based event delivery and turnId stamping
- Agent manager: identity-based turn ownership via activeForegroundTurnId
replacing pendingRun async generator
- Delete: dual queues, routeSdkMessageFromPump, startLiveHistoryPolling,
snapHistoryOffsetToEnd, liveEventBacklog, Pushable
- Fix Codex provider not clearing activeForegroundTurnId on turn completion
- Add real-provider integration tests for event stream invariants
