   * bkit Vibecoding Kit - SessionStart Hook (v2.1.41, uses BKIT_VERSION from lib/core/version)
   *
   * Thin orchestrator that delegates to startup modules:
   *   1. migration   - Legacy path migration (docs/ -> .bkit/)
   *   2. restore     - PLUGIN_DATA backup restoration
   *   3. contextInit - Context Hierarchy, Memory Store, Import Resolver, Fork cleanup, ensureBkitDirs
   *   4. onboarding  - Onboarding message generation, env vars, trigger table
   *   5. sessionCtx  - additionalContext string building for hook output
   *   6. dashboard   - PDCA progress bar rendering (prepended to additionalContext)
   *   7. workflowMap - v2.0.0 Workflow map rendering (PDCA phase visualization)
   *   8. controlPanel- v2.0.0 Control panel rendering (automation level display)
   *   9. staleDetect - v2.0.0 Stale feature detection (lifecycle.js)

  /*
   * v2.1.34: read the hook payload.
   *
   * This handler previously ignored stdin entirely, which cost it two things.
   *
   * First, `source` — Claude Code reports whether the session began via
   * `startup`, `resume`, `clear`, `compact` or `fork`. bkit had no way to tell
   * them apart, and the `once: true` flag it carried in hooks.json to approximate
   * "only on a fresh session" was never honoured there in the first place (it is
   * read only from skill frontmatter). Confirmed by resuming a session and
   * watching this hook fire a second time.
   *
   * Second, dispatch observability: reading through the shared reader stamps
   * `.bkit/runtime/hook-dispatch.ndjson`, which is how the host-integration test
   * proves from the outside that Claude Code really invokes this hook. A hook
   * nobody can observe is how eight bkit features stayed dead across releases.
   *
   * The reader is bounded (issue #139), so this cannot stall the session.
