xsser d40ca8a164 feat(pua): add silent heartbeat stats ...

Summary:
- Add a silent SessionStart heartbeat hook that posts minimal anonymous
  install activity to Cloudflare without emitting stdout, stderr, or
  additionalContext.
- Add the Cloudflare Pages heartbeat endpoint, D1 migration, and
  admin-only stats page at #/admin/heartbeats.
- Add heartbeat regression gates, release consistency checks, FAQ/design
  notes, and bump marketplace/package versions to 3.4.3.

Rationale:
- Active-user measurement belongs in a hook-side mechanical gate, not in
  the model prompt, so the worker context cannot narrate or leak the
  telemetry behavior.
- Privacy gates disable the signal for offline mode, telemetry opt-out,
  and feedback-off users before any local telemetry identity is created.

Tests:
- bash evals/test-heartbeat.sh
- bash evals/test-release-consistency.sh
- static eval suite: governance, feedback auth, integrity guard, issue
  regressions, Microsoft flavor, platform compat, loop hook, Windows
  Python hooks, YAML frontmatter
- bash evals/test-behavior.sh
- npm --prefix landing run build
- ./landing/node_modules/.bin/tsc -p pi/pua/tsconfig.json
- git diff --check
