Windows: first native release (updater + dictation + UX polish)

[amanthanvi]

Summary

Track shipping the first fully functioning native Windows (x86_64) release of CodexMonitor, including the required auto-updater + dictation milestone items and Windows UX correctness.

In-repo sources of truth:

• SPEC.md (requirements + acceptance criteria)
• PLAN.md (execution plan / checklist)

Goals (this milestone)

• Auto-updater functional on Windows.
  • Windows assets attached to GitHub Releases.
  • latest.json includes a windows-x86_64 entry with correct URL + signature.
  • Updater uses the NSIS installer (.exe + .exe.sig) bundle.
• Dictation functional on Windows.
  • Whisper-based backend (whisper-rs + cpal).
  • Same UX + model lifecycle/events as other platforms.
• Windows UX correctness.
  • Explorer/Finder strings are platform-aware.
  • “Open in …” works with common Windows shims (code.cmd, etc.).
  • Shortcut hints/labels are Windows-friendly (Ctrl/Alt; no macOS-only glyphs).
  • Dark/Dim theme selects remain readable with Reduce Transparency off.

Non-goals

• Authenticode / EV code signing.
• Windows ARM64 builds.

Implementation

A PR will land the changes described in SPEC.md / PLAN.md (branch: feature/windows-support).

Acceptance criteria

• npm run tauri:build:win succeeds on Windows 10/11 x86_64.
• Release workflow publishes Windows installers + updater signatures and includes Windows in latest.json.
• In-app updater downloads and installs the latest Windows release.
• Dictation works end-to-end on Windows (download → hold-to-talk → transcript).
• Adding a workspace works when codex --version works in Windows Terminal.

Verification notes

• JS/TS validation is run locally: npm run lint, npm run test, npm run typecheck.
• Rust/Windows compilation and packaging are validated via the Windows build + CI jobs.
