Add pi (https://github.com/badlogic/pi-mono) as a supported source. Pi is a terminal-based AI coding agent. Integration is via a TypeScript extension (codeisland-pi.ts) that forwards pi lifecycle events to the CodeIsland Unix socket, following the same hook-event protocol as other supported tools. Changes: - SessionSnapshot: add "pi" to supportedSources and displayName - AppState: add findPiPids() and route "pi" in findPids(forSource:) - Resources: add codeisland-pi.ts extension and pi.png icon placeholder The extension maps pi events to CodeIsland hook_event_names: session_start → SessionStart session_shutdown → SessionEnd before_agent_start → UserPromptSubmit tool_call (safe) → PreToolUse tool_call (dangerous) → PermissionRequest (blocking via bridge) tool_result → PostToolUse agent_end → Stop session_before_compact → PreCompact session_compact → PostCompact Installation: drop codeisland-pi.ts into ~/.pi/agent/extensions/ and reload pi with /reload. No settings.json changes required. Note: pi.png is a placeholder — a proper pixel mascot and icon can be contributed as a follow-up.

Summary
Add pi as a supported source.
Pi is a terminal-based AI coding agent built with Node.js. Integration uses the existing CodeIsland Unix socket hook-event protocol — no new protocol or app architecture changes are required.
How it works
A TypeScript extension (
codeisland-pi.ts) runs inside pi and forwards lifecycle events to the CodeIsland socket, following the samehook_event_nameconvention as all other supported tools.hook_event_namesession_startSessionStartsession_shutdownSessionEndbefore_agent_startUserPromptSubmittool_call(safe)PreToolUsetool_call(dangerous bash)PermissionRequest(blocking via bridge)tool_resultPostToolUseagent_endStopsession_before_compactPreCompactsession_compactPostCompactChanges

CodeIsland picks up pi sessions automatically — no further configuration needed.

pi.pngis a placeholder; a proper pixel-art mascot can be contributed separatelyConfigInstallerauto-install support (like OpenCode) can be added as a follow-up once the core integration is validated
