andrew 2df578eab8 Delete __run__ branches on every terminal state (MR-674)
Run branches are transactional scaffolding — the durable audit lives
on RunRecord. Invariant: every terminal state (Published, Aborted,
Failed) deletes the __run__ branch.

- Add `terminate_run` helper: appends terminal RunRecord, then
  deletes the run branch. Delete errors are swallowed — the record
  is authoritative; `cleanup_terminal_run_branches_for_target`
  retries on later `branch_delete` of the target.
- Wire into `publish_run_as`, `abort_run`, `fail_run`.
- Include `Failed` in the cleanup filter (was `Published | Aborted`
  only) for legacy-repo GC during branch_delete.
- Cleanup now checks `coordinator.all_branches()` first to skip
  branches already deleted by a concurrent handle — avoids Lance
  NotFound when two handles publish/clean up independently.
- Drop `Failed` from `ensure_branch_delete_safe` — post-fix, Failed
  means the branch is already gone, so there's no reason to block
  target deletion (MR-674 "Downstream effects").

Tests:
- New regression: `run_branches_do_not_accumulate_across_repeated_loads`
  — 10 loads + 1 abort → `branch_list() == ["main"]`.
- New `failed_load_deletes_run_branch` asserts Failed path cleans up.
- Rename `abort_run_keeps_target_unchanged_and_preserves_hidden_branch_for_inspection`
  → `abort_run_leaves_target_unchanged_and_deletes_run_branch`, invert
  the hidden-branch assertion.
- Rewrite `public_{load,mutation}_preserves_staged_edge_ids_on_publish`
  to capture staged IDs before publish instead of inspecting the run
  branch after (branch is gone now).
- Update MR-670 regression test to assert the run branch is *absent*
  after publish.

Deferred to follow-up: `--keep-run-branch` debug flag, `omnigraph run gc`.
