v0.15.2

## Release Notes

### Improved

- **`wt config shell completions <shell>`**: Generate static shell completion scripts for package managers and custom installation. ([#701](https://github.com/max-sixty/worktrunk/pull/701), thanks @chenrui333)
- **Debug logging threshold**: Now requires `-vv` instead of `-v` for debug logging and diagnostic file generation, freeing `-v` for future use. ([#702](https://github.com/max-sixty/worktrunk/pull/702))

### Fixed

- **Fork PR fetching**: `wt switch pr:N` now works when `origin` points to a fork by fetching PR refs from the upstream remote. Shows actionable error with `git remote add` command if upstream remote is missing. ([#704](https://github.com/max-sixty/worktrunk/pull/704))
- **Fork PR branch naming**: Fork PR branches now use the original branch name (e.g., `feature-fix`) instead of `owner/feature-fix`, so `git push` works correctly. ([#706](https://github.com/max-sixty/worktrunk/pull/706))
- **Config race conditions**: File locking prevents corruption when multiple `wt` processes modify config simultaneously. ([#693](https://github.com/max-sixty/worktrunk/pull/693))
- **Nested worktree detection**: Current worktree indicator (`@`) now shows on the correct worktree when worktrees are nested (e.g., `.worktrees/` layout inside repo). ([#697](https://github.com/max-sixty/worktrunk/pull/697))
- **Symlink path resolution**: Worktree commands work correctly on systems with symlinks (e.g., macOS `/var` → `/private/var`). ([#696](https://github.com/max-sixty/worktrunk/pull/696))
- **Pre-remove hook failures**: Shell no longer cd's to main worktree when pre-remove hooks fail, leaving user in their current location. ([#692](https://github.com/max-sixty/worktrunk/pull/692))
- **PowerShell completion robustness**: Completion registration errors no longer break the shell wrapper function. ([#674](https://github.com/max-sixty/worktrunk/pull/674))

### Documentation

- Added missing `orphan` (`∅`) symbol and `no_worktree` state to JSON output documentation. ([#687](https://github.com/max-sixty/worktrunk/pull/687))
- Clarified Unicode handling in shell detection. ([#700](https://github.com/max-sixty/worktrunk/pull/700))

### Internal

- Refactored large files into focused modules. ([#688](https://github.com/max-sixty/worktrunk/pull/688))
- Consolidated integration reason computation into Repository method. ([#689](https://github.com/max-sixty/worktrunk/pull/689))
- Added verbose level tracking infrastructure for future `-v` output. ([#703](https://github.com/max-sixty/worktrunk/pull/703))
- PowerShell template uses `WORKTRUNK_BIN` for test isolation. ([#674](https://github.com/max-sixty/worktrunk/pull/674))
