🧩 Task: Document preparation-phase invocation visibility

Automated task PR opened by Code UX for T06.

📋 Summary

Sprint: Sprint 220 · Reduce invocation visibility latency safely · Task: T06

Make CLI task-coding execution invocations server-visible immediately after cancellation registration and before workspace preparation, while preserving truthful provider telemetry, recovery semantics, server-authoritative dashboards, and realtime Stats freshness.

📝 Full Task Prompt

## Objective
Bring architecture, dashboard, and public realtime documentation into agreement with the new CLI invocation lifecycle and Stats refresh behavior.

## Scope
- `docs/architecture/execution-invocation-tracking.md`
- `docs/architecture/dashboard-realtime-transport-plan.md`
- `docs/dashboard/design-system-stats.md`
- `docs-web/architecture/execution-invocation-tracking.md`
- `docs-web/user/dashboard/stats.md`
- `docs-web/developer/websocket-realtime.md`
- Generated `docs-web/content/docs/` artifacts produced by the repository documentation sync command

## Implementation Requirements
1. Explain that a CLI execution invocation may become visible during cancellable workspace/provider preparation, while provider usage `started_at`, duration, concurrency, and token telemetry begin only at provider claim/run time.
2. Document truthful preparation, failure, cancellation, shutdown recovery, resumed-workspace recovery, and one-to-one provider linkage semantics.
3. Document Chat's server-authoritative invocation records, Stats System invalidation on `project.execution.updated` and `snapshot_required`, and Live's retained five-second heavy snapshot throttle.
4. Run the repository's docs synchronization and validation commands so matching public/generated pages remain consistent without changing navigation unnecessarily.

## Constraints
- Use generic project wording and do not expose live project names or secrets.
- Keep the existing architecture terminology and navigation structure.
- Do not document provider activity before the provider has actually claimed a slot or started.

## Verification
- Run `pnpm run sync:docs-web`.
- Run `pnpm run check:docs-web` and inspect the affected canonical and public pages for matching lifecycle language.
- Run `pnpm run lint` if generated TypeScript or route artifacts are touched.
