## Prompt

Continue PR #481 review remediation after committing the debugger-state
sampler. The human selected "keep" for the paired review request to use
`Aid` objects as keys in the newly added reap-coordination maps.

## Response summary

Migrate only `ActorNursery._child_reap_requests` and
`ActorNursery._child_reaped` to `Aid` keys. Preserve the legacy
`ActorNursery._children` `.uid` key and pass full actor identities
through the narrow process-monitor bookkeeping path.

## Files changed

- `tractor/runtime/_supervise.py` - key fresh reap maps by `Aid`.
- `tractor/spawn/_spawn.py` - pass `Aid` into completed-reap cleanup.
- `tests/test_to_actor.py` - exercise `Aid` registration keys.

## Human edits

The human explicitly selected "keep" after reviewing the scope,
performance, and mutability tradeoffs. The human retained the legacy
tuple key for `_children` and accepted `Aid` for only the two fresh
private mappings. No direct source-line edits were made by the human.
