Replace the boolean isGitRepository() check with a tri-state Git detection so environmental git failures (dubious ownership, missing git binary, timeouts) are no longer misreported as "not a Git repository", which previously blocked all task execution in valid repos and survived engine restarts.
- Add detectGitRepository() in worktree-pool.ts returning repo / not-repo / error (with reason: dubious-ownership, git-missing, timeout, unknown), classified from git's stderr; bound the git rev-parse call with a 10s timeout and maxBuffer; keep isGitRepository() as a backward-compatible wrapper
- Route the executor dispatch preflight guard through detectGitRepository(): only emit the original "not a Git repository / run git init" fatal on a positive not-repo verdict; on error, throw a distinct accurate error naming the real git failure, including the safe.directory remedy for dubious ownership
- Route the in-process runtime startup warning through the same tri-state detection so it only warns "not a Git repository" on a positive not-repo verdict
- Add a regression test locking extractWorktreeConflictInfo() to NOT misclassify a dubious-ownership git worktree add failure as not-git-repo
- Add targeted tests across worktree-pool, executor-worktree, and in-process-runtime test suites covering repo/not-repo/dubious-ownership/git-missing/timeout classifications on Windows OneDrive-style and POSIX paths
- Add changeset and a docs/solutions/logic-errors write-up of the false-negative root cause and fix
