## Prompt

Continue PR #481 review remediation after committing the paired
`ActorNursery` reap-state invariant. The human selected "keep" for the
reviewer's request to factor a duplicated debugger predicate in
`_try_cancel_then_kill()`.

## Response summary

Factor the child/tree debugger predicate into a local sampler used both
before and after the cancel-RPC checkpoint. Preserve dynamic debugger
lock re-evaluation and its distinction from root-wide debug mode.

## Files changed

- `tractor/runtime/_supervise.py` - factor the duplicated debugger
  predicate without changing cancellation behavior.

## Human edits

The human explicitly selected "keep" after receiving keep/defer/drop
options for this isolated review item. During commit-plan review, the
agent found that a single pre-checkpoint snapshot could become stale;
the human selected a local helper which re-evaluates the lock after the
cancel RPC. The human then considered moving the predicate into
`.devx.debug` and accepted keeping it local after confirming that no
existing helper shares its supervisor-owned semantics. No direct
source-line edits were made by the human.
