v5.1.1

Patch Changes

• 387b05e: Fix 20 code-review findings across safety, CLI, MCP, and config subsystems (F1–F20 in REVIEW_FINDINGS.md): orphan cleanup can no longer delete a bare repo nested in worktreeDir; filesToCopyOnBranchCreate works again (patterns stay relative, absolute/escaping patterns rejected); default branches containing / are detected correctly; MCP create_worktree/update_worktree fetch before acting; runOnce exit codes no longer mask failures (SIGINT exits 130, per-repo runOnce rejected in favor of defaults.runOnce); diverged-replace preserves stashes; trash pin refs are namespaced per trash root; config validation rejects malformed branchInclude/branchExclude/branchMaxAge/parallelism values; .cjs configs hot-reload; plus assorted smaller fixes (retry classification, timing table, init wizard validation, LFS sampling, metadata guard, MCP registration probing).
