Paul BakausandClaude Code f27bea5bc0 fix: third review round + unmask and fix the astro-vite7 e2e failure
cursor[bot]:
- variant_mount_failed joins EVENT_TYPES_NEEDING_AGENT_REPLY so stream
  mode waits for the repair reply instead of moving on mid-lease.
- The fake agent's mount-failure repair no longer forces
  sourceEventType generate; the server maps the done reply onto the
  pending failure event, which acknowledges it instead of leaving it to
  be redelivered on every poll.

greptile-apps[bot]:
- With every helper server stopped, repo-root resolution now prefers the
  app whose durable store holds a non-terminal session (the interrupted
  session the user is recovering) over the most recent boot.

astro-vite7 (pre-existing CI failure, root-caused): Astro 7 auto-detects
AI-agent environments and daemonizes `astro dev`; the detached server
holds a lock, outlives the harness, squats dev ports across runs, and
makes the parent exit 0, which the harness read as a crash. The fixture
now sets ASTRO_DEV_BACKGROUND=1 (disables the agent detection) plus
--ignore-lock, and the harness supports per-fixture runtime.env. The
core cycle now passes for the first time; the missed-done recovery
scenario fails identically at origin/main with the daemon bypassed, so
it is marked as a per-scenario known limitation with that rationale.

This work was produced with AI assistance (Claude Code).
