dh 9542c05ea4 feat(macos): add native desktop controls and hotkey integration
- Introduced MacOsDesktopControlManifest to manage desktop control configurations.
- Implemented MacOsDesktopControlService to handle the lifecycle of the macOS helper process.
- Created MacOsWorkflowRulesEditorWindowService for managing workflow rules through a native window.
- Developed a Swift helper for macOS that integrates with AppKit and Carbon for menu-bar controls and global hotkeys.
- Added support for recording lifecycle actions via HTTP endpoints, maintaining consistency with existing Windows functionality.
- Enhanced user experience by allowing macOS users to start/stop recordings and access settings through a menu-bar interface.
- Documented design decisions, implementation evidence, and verification tasks for the new macOS features.

# Implementation Evidence
## Automated
- `dotnet test MeetingAssistant.Tests/MeetingAssistant.Tests.csproj --filter FullyQualifiedName~MacOsDesktopControlManifestTests --no-restore`
- Passed: 1, Failed: 0.
- `dotnet build MeetingAssistant/MeetingAssistant.csproj -f net10.0 --no-restore`
- Passed and produced `Native/macos-desktop-controls` as an arm64 Mach-O executable.
- `openspec validate add-macos-desktop-controls --strict`
- Passed.
- Full portable test project:
- Passed: 427.
- Failed: 9 existing macOS/environment-dependent tests: Windows path expectations, unavailable GDI+, and user-environment key resolution.
- Whole solution:
- Cannot build the Windows target on macOS without enabling cross-Windows targeting (`NETSDK1100`).
## Runtime
- Installed the rebuilt application assembly and both native helpers into the existing local LaunchAgent application directory.
- LaunchAgent restarted successfully.
- `/health` returned `ok`.
- `macos-desktop-controls` ran as a child companion process.
- The helper manifest contained six configured hotkeys, including the unchanged defaults `Ctrl+Alt+M`, `Ctrl+Alt+L`, `Ctrl+Alt+Z`, and `Ctrl+Alt+S`.
- A fresh default-profile recording request created the `20260724-2015` meeting note and linked artifacts.
- Screenshot evidence: `tmp/macos-desktop-recording-verification.png`.
## Live desktop-control proof (2026-07-24)
- The installed LaunchAgent ran:
- `.NET host` PID `23023`
- native `macos-desktop-controls` PID `23097`
- The native helper manifest exposed:
- `Ctrl+Alt+M` -> `/profiles/default/recording/toggle`
- `Ctrl+Alt+L` -> `/profiles/english/recording/toggle`
- `Ctrl+Alt+Z` -> `/profiles/default/recording/abort`
- `Ctrl+Alt+S` -> `/profiles/default/meetings/screenshot/capture`
- Accessibility inspection of the real AppKit menu returned:
- `Meeting Assistant — idle`
- `Open agent`
- `Start meeting recording (default)`
- `Start meeting recording (english)`
- `Exit`
- Visible menu screenshot:
- `tmp/proof-macos-menu-idle.png`
- The menu visibly displays the macOS equivalents `⌃⌥M` and `⌃⌥L`.
- Clicking `Start meeting recording (default)` through the real menu produced the sampled status transition `false,true,false`, with `launchProfile: default`, and created:
- `Meetings/Notes/20260724-2022-note.md`
- `Meetings/Transcripts/20260724-2022-transcript.md`
- `Meetings/Assistant Context/20260724-2022-context.md`
- Posting the HID-level `Ctrl+Alt+M` combination produced the sampled status transition `false,true,false`, with `launchProfile: default`.
- Posting the HID-level `Ctrl+Alt+L` combination produced an active sampled state with `launchProfile: english`.
- Raw sampled status evidence:
- `tmp/proof-menu-recording-status.jsonl`
- `tmp/proof-hotkey-recording-status.jsonl`
- `tmp/proof-english-hotkey-status.jsonl`
## Runtime limitation
The new recording did not remain active because the local audio capture process stopped shortly after artifact creation. The desktop-control helper, menu-bar item, endpoint routing, and meeting creation were verified; sustained audio capture was not.
## Open agent regression and runtime proof
- Original deterministic regression:
- `MacOsApplicationRegistersARealInteractiveAgentWindow`
- Red result: portable registration resolved exactly `NoopWorkflowRulesEditorWindowService`.
- Fix:
- macOS now registers `MacOsWorkflowRulesEditorWindowService`.
- `Open agent` in the native helper creates an AppKit `NSWindow` titled `Meeting Summary Agent`.
- The window hosts a WebKit chat page backed by the existing `WorkflowRulesEditorChatViewModel` and agent pipeline.
- Green regression:
- Passed: 1, Failed: 0.
- Live installed runtime:
- Clicking the actual menu item created an on-screen CoreGraphics window:
- owner: `macos-desktop-controls`
- title: `Meeting Summary Agent`
- layer: `0`
- bounds: `756x714`
- `GET /diagnostics/settings-and-logs` returned the interactive agent HTML page.
## Open agent prompt execution proof (2026-07-25)
- Original live failure:
- `Meeting Summary Agent failed: No workflow rules editor API key configured.`
- Root cause:
- The LaunchAgent did not inherit the interactive shell's model API key.
- Its configured `127.0.0.1:4021` model endpoint had no running service.
- Runtime configuration:
- The protected LaunchAgent environment file now supplies the local LiteLLM gateway key.
- `MeetingAssistant__WorkflowRulesEditor__Endpoint` targets the running local gateway on port `4000`.
- The local gateway exposes the Responses-compatible `chatgpt-gpt-5.5` model alias.
- Event-stream compatibility regression:
- `ClientReconstructsResponseFromServerSentEvents` failed before the fix with `JsonReaderException`.
- The client now reconstructs completed response items from LiteLLM server-sent events.
- All 11 `LiteLlmResponsesChatClientTests` pass.
- Live installed proof:
- `POST /diagnostics/settings-and-logs/chat` with `Reply with exactly: key-ok`
returned `{"role":"agent","content":"key-ok"}`.
- `/health` returned successfully after deployment.
