GAM 7.48.05 (automated bump)

[github-actions]

Automated bump of the vendored GAM, 7.48.02 → 7.48.05, via scripts/bump_gam.py.

• Asset build-attestation verified against GAM-team/GAM before the pin was written.
• Pin, version strings, test mock, browse catalog and CLAUDE.md counts updated mechanically.
• ✅ offline suite green

Before merge (human): skim the changelog below, and run scripts/acceptance.py against a
real tenant — CI cannot (it is the only true output-shape check). If the suite is red, the
contract test likely caught a renamed/removed command we use; that needs a code change.
