Bumps pyasn1 from 0.6.4 to 0.6.5.

Release notes

Sourced from pyasn1's releases.

Release 0.6.5

Revision 0.6.5, released 26-10-2026

• GHSA-mm57-4v3p-rchx: Decoded binary REAL mantissas in linear time instead of repeatedly shifting a growing integer and slicing the remaining bytes (thanks for reporting, manus-use, manus-pi, ucsurf, adriank31)
• GHSA-2qm8-x737-gmw5: Reassembled constructed BIT STRING fragments in linear time while preserving their decoded bit values, including intermediate fragment padding (thanks for reporting, manus-use)
• GHSA-9m75-vc3g-4x39: Reassembled constructed OCTET STRING and character-string fragments and indefinite-length ANY content in linear time. Nested constructed OCTET STRING fragments now contribute their decoded octets (thanks for reporting, alimony, manus-pi, adriank31)
• GHSA-fm9c-5rcf-2q5p: Bounded schemaless container type tracking after two distinct tag sets to prevent quadratic CPU use from colliding long tag IDs (thanks for reporting, droideck)

Reviewed commit 21886dfe6c4ad03de31ff0622be38a94618f34f1.

The pyasn1 bump also removes platform-dependent pins from the universal development lock. In particular, culsans==0.11.0 ; python_full_version < '3.13' disappears, along with aiologic, sniffio, wrapt, Windows colorama, and other baseline entries/markers.

The current-head Python 3.11 CI job fails during pip install --require-hashes -r requirements/dev.txt: a2a-sdk[http-server]==1.2.2 requires culsans>=0.11.0, but the PR no longer supplies its exact version and hashes. This occurs before tests run.

Regenerate from requirements/dev.in with the documented --universal --python-version 3.11 command, preserving the conditional dependency inventory, and validate clean hash-locked installs on the supported Python/platform matrix. #303 already contains a reviewed universal-lock repair and the public-extra pyasn1 floors; coordinating with that PR may avoid a second competing repair. The desired pyasn1 version is not the blocker here; the incomplete regenerated lock is.

[dependabot]

Looks like pyasn1 is up-to-date now, so this is no longer needed.
