Remove per-repo lock from task dequeue and global concurrency cap from worker loop. Each task already runs in an isolated worktree, so there's no need to serialize tasks per repo or cap total concurrency.
- Per-repo mutex in RepoManager serializes clone/pull/worktree-create so concurrent tasks on the same repo don't hit git lock contention. The lock releases before the agent runs, so execution is still parallel. - Atomic dequeue via SQLite transaction prevents duplicate task dispatch when multiple dequeue calls race. - 100ms sleep between task spawns prevents burst-spawning all queued tasks simultaneously. - Outer worker catch now cleans up task state (queue.fail, delete from runningProcesses/pendingReplies) instead of just logging. - Worktree cleanup failures are logged instead of silently swallowed.

Reconcile PR #20 (parallel tasks) with waiting_user blocking. Only block dequeuing from repos that have a waiting_user task (live session waiting for input), not from repos with running tasks. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
