Mesut Oezdil f084eb39cb fix(sbom): release lock before sleeping in _rate_limit (#1896)
* fix(sbom): release lock before sleeping in _rate_limit

time.sleep was called inside the _rate_lock block, blocking all threads
from checking their own domain rate limit while one thread slept.
With _MAX_WORKERS=12 querying crates.io, npm, and pypi concurrently,
this made the thread pool effectively serial.

Move the sleep outside the lock so threads for different domains
can proceed concurrently.

* fix(sbom): reserve next slot in _rate_limit to prevent same-domain races

Use time.monotonic() and store next_req = max(now, last + interval) so
concurrent same-domain callers each get a unique future slot rather than
all sleeping the same amount. Add regression tests for same-domain
spacing and different-domain non-blocking.

* fix(sbom): wire rate-limit tests into test suite via test:sbom task

Rename test_resolve_licenses.py to resolve_licenses_test.py to match
repo *_test.py convention. Add test:sbom task to tasks/test.toml and
include it in the top-level test depends so mise run test picks it up.

* fix(sbom): add SPDX header, fix cross-domain regression test to exercise lock contention

* fix(sbom): replace zip with itertools.pairwise to satisfy ruff lint
