David Kong a18e6fe64a Milestone 2.1: Implement git_worktree_create tool (#4) (#17)
## Summary
Implements the `git_worktree_create` tool with full validation and error handling per issue #4 acceptance criteria.

## Changes
- New `pi-worktree-create.ts` module with pure, testable functions (no pi SDK deps)
- `validateCreateWorktreeInput()` — validates path and branch name parameters
- `validatePathDoesNotExist()` — refuses if target path exists (injectable for testing)
- `isCurrentBranch()` — prevents creating worktree on current branch
- `buildWorktreeAddCommand()` — builds correct git command with `-b` flag support
- Integrated all helpers into `createCreateWorktreeTool()` in main extension
- 17 new tests covering all validation paths and edge cases (29 total, all passing)

## Testing
- [x] All 29 tests pass (`bun test .pi/extensions/*.test.ts`)
- [x] Full test suite run with no regressions
- [ ] Manual verification (requires pi runtime)

## Checklist
- [x] Self-reviewed the diff
- [x] Code follows project conventions
- [x] Descriptive naming (no single-character variables)
- [x] Documentation updated (JSDoc on all new functions)
