feat: Claude Code Monitor — lanes, pipelines and a merged workspace

Internal SmartGift build of a Claude Code monitoring dashboard.

Lanes: a durable unit of parallel agent work, one per working directory,
tracked across session restarts. Managed lanes are git worktrees the
dashboard provisions and can reset or remove behind a three-check destroy
guard and a counted preflight; adopted lanes are directories you already
own and are never destroyable.

Pipelines: a lane moves through pipeline stages. A stage the agent declares
with evidence renders green; a stage inferred from the tool-event stream
renders dashed amber and never counts as done. Detection is forward-only
within a 30-minute window, and never writes the declared stage.

Workspace: one page at /run with a lane grid, the selected lane's pipeline,
and a full Claude console behind a disclosure.

/**
* @file tuiSegments.ts
* @description Parses Claude TUI tag markup that appears in user messages -
* caveats, command invocations, captured stdout/stderr, system reminders -
* into a flat segment list the renderer can lay out inline. Also strips bare
* ANSI/SGR escape sequences (e.g. "[1m...[22m") that survive the JSONL pipe
* so messages render as plain text instead of leaking codes.

/* =============================================================================
* MODULE_GUIDE — extended in-file reference (comments only; safe to read, never executed)
* =============================================================================
* **Purpose:** Renders Claude transcript rows (user, assistant, tool calls) inside Session Detail with markdown, syntax highlighting, and TUI-style segments.
*
* ## Design constraints
* - Local-first: no telemetry leaves the machine unless the user configures webhooks.
* - Fail-safe hooks path on the server must never block Claude Code; UI mirrors that
* philosophy by degrading gracefully (empty states, stale badges, reconnect loops).
* - Destructive flows stay behind explicit confirmation modals and server-side gates.
* - Internationalization: user-visible strings belong in i18n JSON, not literals here.
*
* ## Remote data & SSH
* Remote Data Sources let operators aggregate multiple machines. SSH entries describe
* how to reach a peer dashboard; the global data scope (`dataScope.ts`) narrows every
* scoped GET via `?sources=`. Health checks and import history surface in Settings.
*
* ## Observability
* Prometheus scrapes `GET /api/metrics` (see `monitoring/`). Grafana ships four
* provisioned boards (overview, sessions, tools, alerts). Native npm scripts and
* Docker Compose profiles are documented in `monitoring/README.md`.
*
* ## Public surface
* - `TuiSegment` — exported API; see TSDoc on the symbol for behavior.
* - `stripAnsi` — exported API; see TSDoc on the symbol for behavior.
* - `parseTuiSegments` — exported API; see TSDoc on the symbol for behavior.
* - `hasTuiTags` — exported API; see TSDoc on the symbol for behavior.
*
* ## Testing pointers
* - Prefer colocated `__tests__` with Vitest + Testing Library for UI.
* - Server contract changes require `npm run test:server` and OpenAPI sync.
* - MCP edits: `npm run mcp:typecheck` and `npm run mcp:build`.
*
* ## Related docs
* - `ARCHITECTURE.md` — hooks → API → SQLite → WebSocket → UI pipeline.
* - `docs/API.md` — REST reference.
* - `.claude/skills/file-headers/` — mandatory `@author` header policy.
