Cancellation after `Start` publication but before `StartAck` can
strand the caller context and leave its remote task running.
Make one shielded, bounded task-cancel request before dropping
local startup state. Keep the private `cancel_on_startup` policy
outside public target kwargs and disable it for the `_cancel_task`
RPC itself so cleanup can not recursively cancel its own startup.
Release each private helper context on exit and prove the
caller-owned actor remains reusable after controlled startup
cancellation.

Derive the `Actor._contexts` key from each `Context` in one
idempotent `Actor._drop_context()` helper instead of reconstructing
the peer UID and CID at every teardown site.
Use the helper for caller-side context exit and preserve a strict
identity assertion when the callee-side RPC task deregisters
itself. Keep channel closure and cancellation shielding with their
existing lifecycle owners.

`SendStream.send_all()` can raise `trio.Cancelled` after writing an
arbitrary prefix of the four-byte length header and payload. The
peer can no longer distinguish a following msg boundary.
Close the stream under a shield before propagating cancellation so
callers can not append another msg to an indeterminate byte stream.

Give each `ActorNursery` child its own reap request and
completion event. Owned one-shots now wait for process joining and
bookkeeping removal before returning.
Escalate unacknowledged cancellation with `proc.kill()` after an
active debugger releases. Latch nursery-wide teardown for monitors
that finish startup late, and snapshot children before cancellation
checkpoints permit concurrent removal.
Cover immediate managed-nursery cleanup, failed cancel
acknowledgements and late monitor registration across Trio TCP/UDS
and `mp_spawn`.

Bring the transport helpers back in line with project style:
- restore single-quote strings and docstrings;
- drop the oversized helper divider and simplify comments;
- keep guarded `match` dispatch so a missing `socket.AF_UNIX`
remains safe when `HAS_UDS` is false.
Also, format the `HAS_UDS` conjunction with the project's
multiline branch convention.

Block the final user on its cached resource's `__aexit__()` and
raise regular cleanup errors at that user's ctx boundary.
Deats,
- serialize user registration and teardown under each cache-key lock
- keep queued entrants on the same lock through resource replacement
- preserve `Cancelled`, `KeyboardInterrupt`, and `SystemExit` flow
- cover successful, failing, cancelled, and re-entry teardown paths
