Customizable Source Control AI action recipes with per-action agent and command templates (#4868)

* WIP: Changes before auto-review fixes

* Customize Source Control AI action recipes

- Add per-action CLI arguments for generation and launch flows so saved
  recipes can select model flags without putting prompts in argv.
- Share the text-generation dialog between commit messages and hosted-review
  details, with first-run defaults and repo/global recipe support.
- Launch fix-check agents directly from saved recipes and harden prompt/template
  handling for invalid args, blank prompts, and inherited variables.

* Allow custom commands for source control action recipes

- Let text action recipes save and resolve the custom-command sentinel
- Add settings UI for custom command recipes and preserve per-action defaults
- Split large source-control dialogs and direct launch helpers into focused modules
- Keep launch actions from treating custom text agents as runnable TUI agents

* Add per-repo Source Control AI enablement, custom command, and save-targ

- Repo overrides now support `enabled` and `customAgentCommand`, letting
  repositories opt in/out of Source Control AI independently and supply a
  repo-scoped custom command that takes precedence over the global one.
- Recipe-save dialogs gained a save-target selector ("Don't save / Save for
  this repo / Save as global default") replacing the old boolean checkbox,
  routing saves through the new `saveSourceControlActionRecipe` helper in
  `source-control-ai-recipe-save.ts`.
- `normalizeRepoSourceControlAiOverrides` now returns `undefined` for empty
  objects and passes the `null` sentinel through the IPC/RPC layer so the
  persistence layer can clear repo overrides cleanly.
- `resolveSourceControlLaunchPlatform` resolves the correct shell platform
  for SSH and WSL worktrees so agent launch commands are built correctly.
- Settings UI gained `RepositorySourceControlAiEnablement` and
  `RepositorySourceControlAiCustomCommand` rows; draft/label logic was
  extracted into focused modules to stay within lint line limits.

* Extract action recipe defaults into own component and use id-prefixed wo

- Move action recipe draft state and UI out of CommitMessageAiPane into SourceControlAiActionRecipeDefaults and source-control-ai-action-recipe-draft.ts to respect the max-lines lint rule
- Use toRuntimeWorktreeSelector() across all runtime git RPC calls so the runtime can resolve worktrees by ID rather than path
- Fix SSH launch platform resolution to use the repo's connection when the newly created worktree isn't hydrated yet
- Add edit and delete handlers for PR conversation comments with confirmation dialog
- Use text-status-success design token instead of hardcoded text-emerald-500

* add more search keyword

* Rename "Enable Source Control AI defaults" to "Show Source Control AI ac

* fix test

* Remove unused imports and variable assignment in launch-work-item-direct

* Fix test mocks to use `mocks.store` instead of `storeState.value` for di

* Extract Source Control AI logic into focused modules with fix-checks dia
