Implement the approved PR #481 review refactor in
`_try_cancel_then_kill()` without changing debugger behavior.

> `git diff HEAD~1..HEAD -- tractor/runtime/_supervise.py`

Compute the child/tree debugger predicate once, reuse it in the broader
hard-kill protection predicate, and pass it directly to
`debug.maybe_wait_for_debugger()`.

Run focused debugger/cancellation coverage and lint after the edit.
