Release v0.45.0

[BenevolentFutures]

Summary

Cuts the v0.45.0 release. Headlines:

• Crash visibility, two new rails. Force-Quit / unclean-exit sentinel under ~/Library/Caches/<bundle-id>/sessions/ (catches the kills Sentry's in-process handler can't see), plus a MetricKit channel that persists MXCrashDiagnostic / MXHangDiagnostic / MXCPUExceptionDiagnostic / MXDiskWriteExceptionDiagnostic payloads to ~/Library/Logs/c11/metrickit/. (#109)
• Main-thread deadlock fixed (4×/day → 0). surface.send_text / send_key / read_text / clear_history no longer park CFRunLoopRun() on main; they run on the socket worker thread and only hop to @MainActor for bounded slices. Hand-port of upstream cmux #3340 with c11-specific allowlist expansion. (#112)
• Worktree-safe Claude Code resume. Restart now records claude.session_project_dir at SessionStart and prefixes the resume command with cd '<path>' &&, so sessions captured inside a worktree subdir actually resume. (#113)
• Menu bar: c11 mark, surface-aware tooltip, no Integrations submenu. (#106)
• Sentry routes to the dedicated stage11-c11 project, with symbolication. Previously dSYM uploads silently no-op'd because SENTRY_ORG / SENTRY_PROJECT pointed at slugs that don't exist; events also landed in a generic demo-project. Now traces land symbolicated, in the right project.
• C11-1 rebrand stragglers. About-dialog source-level fallback, doc-link comments, and legacy icon-generator os.execv targets all corrected. (#111)

Excluded from the changelog as not user-facing: the Sentry/MXMetricPayload Swift-6.2 build gate (#114, CI-only), upstream-triage scaffolding, mailbox-guide docs, README polish, the OpenAI computer-use harness, Dependabot rollups, and the launchd prune-stale-tagged-builds job.

Test plan

• CI green (build + workflow guards + ghosttykit checksums).
• Squash-merge → tag v0.45.0 → release workflow publishes c11-macos.dmg.
• Smoke: launch the released DMG, hover the menu bar, force-quit, relaunch, confirm unclean-exit-*.json appears under ~/Library/Caches/com.stage11.c11/sessions/.
• Smoke: run surface.send_text 50× under load; confirm no main-thread parking under v2AwaitCallback.
