feat(github): configurable quick-action presets and PR branch checkout (#689)

* feat(github): configurable quick-action presets and PR branch checkout

- Add workspace-scoped action presets (icon, label, hint, prompt template) for PRs and Issues, editable from GitHub settings with reset-to-defaults.
- When starting a task from a PR, check out the PR head branch directly in the worktree instead of branching off main.

* fix(github): extract action-preset service to keep service.go under line limit

Splits the preset CRUD methods out of the oversized service.go and applies prettier formatting to three frontend files flagged by CI.

* fix(github): address review feedback on action presets

- Prevent infinite refetch loop when fetching presets fails by tracking attempted workspaces in a ref instead of re-entering the effect on every loading-state change.
- Drop unused savePR/saveIssue helpers from the hook; only save() is consumed.
- Reorder the init spread in updateGitHubActionPresets/resetGitHubActionPresets so callers can't accidentally overwrite method/body.
- Tighten the GitHubActionPreset.icon type with string & {} so known icon keys keep autocomplete.
- Sharpen the eye-icon test to assert the exact IconEye mapping.

* fix(github): address second round of review feedback

- Seed preset editor drafts from current store state via lazy initializers so a warm mount shows the user's saved customisations instead of silently reverting to defaults when Save is clicked.
- Guard Reset button with its own in-flight state to prevent double-firing.
- Stop freezing resolved defaults into the stored row on a partial update; persist only what the store has for the untouched kind so future default improvements still reach those workspaces.

* refactor(github): tighten quick-actions editor UI

Replace the stacked PR/Issue editors and multi-line preset cards with a tabbed layout and single-line rows. Each row shows icon · label · hint inline; an "Edit prompt" toggle reveals the template textarea only when needed. Drops the redundant section headings, up/down reorder buttons, and verbose template helper label (hint moved into the textarea placeholder).

* fix(github): widen icon select trigger so the icon is visible

The icon select trigger had a fixed 40px width which the SelectTrigger's built-in chevron, padding, and icon gap all competed for, clipping the icon out of view. Drop the width override so the trigger sizes to its content.
