fix: make global hotkey press-and-hold reliable - #113

Expose typed Carbon edge events through a generation-fenced registrar with non-destructive probes and replacement ordering. Keep failed candidates from displacing the active registration and make registration failures actionable.

Plan: .omo/plans/issue-82-global-hotkey.md

Track keyboard ownership and startup release intent independently from coordinator state. Suppress duplicate and repeat edges while making processing-state input explicit and keeping mouse-owned recordings isolated.

Plan: .omo/plans/issue-82-global-hotkey.md

Use Shift-Command-Space as the single shipped default, migrate only the legacy Option-Command-Space value, and allow key code zero with supported modifiers. Expose the same readable presentation through the core shortcut contract.

Plan: .omo/plans/issue-82-global-hotkey.md

Capture shortcuts through an AppKit first-responder control with readable modifier glyphs, key-code-zero support, repeat suppression, validation feedback, and Escape restoration. Keep capture local to the explicit recorder surface.

Plan: .omo/plans/issue-82-global-hotkey.md

Route Carbon press and release edges through a keyboard-owned intent bridge, preserve release through asynchronous startup, and share normal stop/finalization with the mouse toggle without canceling on release.

Plan: .omo/plans/issue-82-global-hotkey.md

Use the native recorder in onboarding and Settings, preserve unsaved candidates on close, and surface registration state and actionable failures through the windows and menu bar. Commit settings only after the working shortcut replacement succeeds.

Plan: .omo/plans/issue-82-global-hotkey.md

Remove the obsolete toggle-controller path, keep the issue-3 mouse toggle characterization, derive Settings copy from the canonical shortcut, and document deterministic and native acceptance boundaries for the full issue #82 contract.

Plan: .omo/plans/issue-82-global-hotkey.md

Treat only unmodified Escape as recorder cancellation, preserve modified Escape as a valid key code, and apply Launch at Login before shortcut replacement so a failed shortcut cannot leave registration and settings out of sync. Add the issue #12 compatibility and dogfood handoff matrix with explicit native INCONCLUSIVE boundaries.

Plan: .omo/plans/issue-82-global-hotkey.md

Point the deterministic and issue #12 handoff matrices at the final-SHA recorder evidence, including modified Escape as a valid candidate.

Plan: .omo/plans/issue-82-global-hotkey.md

Point the deterministic and issue #12 handoff matrices at the final native build, launch, and permission-boundary receipts.

Plan: .omo/plans/issue-82-global-hotkey.md

Point the issue #82 and issue #12 handoff matrices at the final verification, recorder, and native receipts that will be bound to the final review SHA.

Plan: .omo/plans/issue-82-global-hotkey.md

Persist the candidate through ShortcutConfigurationTransaction before publishing new in-memory settings, so shortcut registration and stored settings cannot diverge across the later settings update path.

Plan: .omo/plans/issue-82-global-hotkey.md

Point the issue #82 and issue #12 handoff matrices at the final verification and native receipts after the settings persistence fix.
