[claude]

LGTM, routine dependabot bump of two pinned GitHub Actions to their new versions.

Extended reasoning...

Overview

This PR bumps two GitHub Actions to newer pinned SHAs:

• actions/cache from v5.0.5 → v6.1.0 in .github/workflows/ci.yml (mypy cache step)
• actions/setup-python from v6.2.0 → v6.3.0 in .github/workflows/package-availability-check.yml

Both are referenced by full commit SHA with version comments, matching the repo's pinning convention. The actions/cache step retains its existing zizmor: ignore[cache-poisoning] comment.

Security risks

None of note. Actions remain pinned to immutable commit SHAs, and the new SHAs (55cc834... for actions/cache and ece7cb0... for actions/setup-python) correspond to the documented tags in their respective release notes. Both targets are well-maintained official actions/* repos. The actions/cache v6 release migrated to ESM but workflow-side usage is unchanged.

Level of scrutiny

Low. This is a Dependabot-generated GitHub Actions version bump with no code changes — purely CI-only updates that don't affect published artifacts or runtime behavior of the Langfuse SDK.

Other factors

The bug hunting system found no issues. No prior reviewer comments are outstanding. CI itself will exercise both updated actions on this PR.
