Feature: worktree view customization and stability fixes (#805)

* Changes from feature/worktree-view-customization

* Feature: Git sync, set-tracking, and push divergence handling (#796)

* Add quick-add feature with improved workflows (#802)

* Changes from feature/quick-add

* feat: Clarify system prompt and improve error handling across services. Address PR Feedback

* feat: Improve PR description parsing and refactor event handling

* feat: Add context options to pipeline orchestrator initialization

* fix: Deduplicate React and handle CJS interop for use-sync-external-store

Resolve "Cannot read properties of null (reading 'useState')" errors by
deduplicating React/react-dom and ensuring use-sync-external-store is
bundled together with React to prevent CJS packages from resolving to
different React instances.

* Changes from feature/worktree-view-customization

* refactor: Remove unused worktree swap and highlight props

* refactor: Consolidate feature completion logic and improve thinking level defaults

* feat: Increase max turn limit to 10000

- Update DEFAULT_MAX_TURNS from 1000 to 10000 in settings-helpers.ts and agent-executor.ts
- Update MAX_ALLOWED_TURNS from 2000 to 10000 in settings-helpers.ts
- Update UI clamping logic from 2000 to 10000 in app-store.ts
- Update fallback values from 1000 to 10000 in use-settings-sync.ts
- Update default value from 1000 to 10000 in DEFAULT_GLOBAL_SETTINGS
- Update documentation to reflect new range: 1-10000

Allows agents to perform up to 10000 turns for complex feature execution.
