Summary

• replace the permission-checker action flow from "open settings only" to "request permission first, then route to settings when needed"
• add a new IPC endpoint (request-capture-permission-access) that handles screen/camera/microphone/accessibility/input-monitoring with target-specific behavior
• update permission checker UI action labels so not-determined states show "Request Access" and add test coverage for action-mode resolution

Behavior changes

• screen: attempts a lightweight screen-source probe to trigger macOS consent flow, then refreshes status
• camera / microphone: calls systemPreferences.askForMediaAccess when status is not-determined
• accessibility: calls isTrustedAccessibilityClient(true) to trigger system prompt path
• input-monitoring: opens the corresponding system settings page (manual-check path)

Validation

• npm test
• npx vitest run src/lib/permissions/capturePermissions.test.ts src/lib/permissions/permissionActions.test.ts src/lib/screenCaptureAccess.test.ts src/lib/permissions/nativeRecorderErrors.test.ts
