Hotfix prompt box freezes in long-lived sessions

[andrei-hasna]

Summary

• keep prompt input responsive by removing routine cross-thread approval scans
• compact persisted closed-thread event buffers without losing reloadable state
• isolate spawned-child subscriptions to parent subscribers
• reuse the implicit app-server daemon only on an exact Codewith version match

Validation

• six focused TUI regressions on Blacksmith
• four focused app-server lineage regressions on Blacksmith
• full codex-tui and codex-app-server package suites
• affected-crate Clippy, formatting, diff check, and gitleaks

Tracks Todos OPE127-00020. Release target: @hasna/codewith 0.1.87.

[REVIEW] GO — #529 @ 88964ed — lens: correctness+security+gates, reviewer Timon (1 of 1)

Reviewed the complete 10-file diff against freshly verified origin/main 11a0f23, plus the surrounding app-server listener, thread lineage, TUI event-store/routing, daemon-probe, and integration-test source.

Commands and results:

• git log --oneline origin/main..HEAD — exit 0; 13 commits read.
• git diff origin/main...HEAD --stat — exit 0; 10 files, 715 insertions, 56 deletions.
• Full diff of every changed file and surrounding source — read successfully.
• bun install — exit 0; setup only, 521 packages installed. This is not reported as a test result.
• package.json script inventory — exit 0. The repo declares no test gate and no typecheck script; no replacement gate was invented.
• gh pr view 529 --repo hasna/codewith --json statusCheckRollup — exit 0. Final authoritative result: 27 SUCCESS, 3 SKIPPED, 0 failures, 0 pending.

Blocking P0/P1 findings: none.

Non-blocking follow-ups:

• The root package.json declares no test script, so this repository declares no test gate there. It also declares no typecheck script. The required forge checks above are green, so this does not block this candidate.
