v0.13.0

Features

• styre ls shows leftover state on disk. A new styre ls command lists resumable runs (paused waiting on you, out of budget, or interrupted) with resume hints, plus a preview of finished runs (PR-ready or done), and marks any run that's still live.
• styre clean reaps finished runs. Use styre clean <ident> to remove one run's on-disk artifacts (worktree and checkpoint), or styre clean --all to sweep every provably-finished run for the current project; clean never touches ticket status, and it refuses to touch a run that's still in progress.
• --purge closes out the branch too. Add --purge to styre clean <ident> to also delete the local and remote branch (closing its PR); it's opt-in, single-ident only, quietly does nothing if there's no branch or PR, and it will never delete your repo's default branch.
• Resuming a run now actually resumes it. styre run --resume clears the pending "needs you" signal before continuing, so a resumed run picks up where it left off instead of immediately pausing again.
• --inspect reports the right step. When inspecting a run dry-run, styre now correctly points at the failed step instead of showing (none).
• Resuming the same ticket twice is blocked. styre run --resume now takes a lock for the ticket, so a second concurrent resume of the same run is refused instead of corrupting state.
• --fresh no longer gets stuck on old worktrees. styre run --resume --fresh now cleans up a leftover worktree from a previous run before discarding its checkpoint, instead of failing.
• A fresh run leaves a proper checkpoint on crash. styre run now journals directly to the run's durable checkpoint from the start, so a crash, escalation, or block leaves behind a checkpoint you can resume — not an orphaned temp file.
• Re-running a ticket is safer. styre run now refuses to start over a ticket that already has a checkpoint (with a hint to use --resume or --fresh), and holds a per-ticket lock while running so two runs can't collide on the same state.
• Pause outcomes are simpler and more consistent. Runs that get stuck or blocked now pause with a clear, resumable "needs you" status instead of silently going into a handful of inconsistent dead-end states; exit code 75 is now used consistently for every kind of pause.

Bug Fixes

• Re-running a ticket no longer collides on its old branch. styre now detects and frees a leftover worktree still holding a previous run's branch (fixing the "already used by worktree" failure on re-run), while refusing to touch a worktree that's still live or owned by something else.
