[claude]

LGTM, minor Dependabot bump of actions/setup-python pinned to a full SHA.

Extended reasoning...

Overview

This PR bumps actions/setup-python from v6.2.0 to v6.3.0 in .github/workflows/ci.yml, pinned to full commit SHA ece7cb0. Only one line changes in the CI workflow; no code or logic is touched.

Security risks

None. The action reference is pinned to an immutable full commit SHA (not a mutable tag), which is the recommended supply-chain practice. The upstream 6.3.0 release only adds RHEL support, fixes Windows pip cache error handling, and bumps internal deps — none of which alter behavior on the ubuntu-latest runners used here.

Level of scrutiny

Low. This is a routine minor-version dependency bump from Dependabot to a widely used first-party GitHub Action, in CI-only configuration. It does not affect the shipped action itself or any runtime code.

Other factors

No bug reports from the hunting system, no outstanding reviewer comments, and no prior review from me on this PR. The existing E2E job that consumes setup-python covers the change.
