youknowdot fc9f4a9541 Update importlib to CPython 3.15 with native bootstrap callback (#9169)
* Refresh canonical importlib and preserve native import callback

Cache the original builtin __import__ callback so CPython 3.15 importlib's
hierarchical locking uses the existing native parent-initialization path.
Refresh the complete canonical importlib and related test/helper families
from CPython d220409a13b77de7a6c30abe16ea90db01528edc through update_lib.

Preserve both nondecorator importlib guards in the updater. Add explicit
hash-pinned removal of reviewed obsolete canonical files, with full
preflight, dry-run, idempotence and refusal tests. Preserve empty fixtures.

* Complete canonical inspect and types closure for importlib metadata

Refresh whole canonical inspect/types production and related test families
through update_lib after hosted CI exposed stale __cached__ consumers.
Add coroutine and async-generator state getters, with closed-state priority
for reentrant frame-local finalizers, and expose the existing frame-locals
proxy type with its CPython class documentation.

Preserve the optional _datetime and unittest import blocks through a narrow
migration adapter. Retain canonical assertions and existing guards; record
the missing LazyImportType expectation before adding a conditional expected
failure, and capability-skip only the two absent-_testcapi CLI fixtures.

* Reject canonical removal junctions and read UTF-8 manifests

Reject junctions alongside symlinks in the existing path-component preflight and revalidation. Decode removal manifests explicitly as UTF-8. Add regressions for whole-batch refusal, revalidation, and Unicode dry-run/apply/idempotence.
