chore(ci): suppress CodeQL file coverage deprecation warning

[sriramveeraghanta]

Summary

• Adds CODEQL_ACTION_FILE_COVERAGE_ON_PRS: false env var to the CodeQL workflow to explicitly opt into the new default behavior where file coverage computation is skipped on PRs for improved analysis performance.
• Resolves the deprecation warning: "Starting April 2026, the CodeQL Action will skip computing file coverage information on pull requests."

Test plan

• Verify the CodeQL action runs without the file coverage warning on a PR trigger

Summary by CodeRabbit

• Chores
  • Disabled CodeQL file coverage reporting for pull requests.
  • This change reduces noise from per-file coverage reports on PRs while retaining other security scanning and analysis.

Poem

🐇 I nudged a flag in CI tonight,
Coverage whispers out of sight,
CodeQL hums its steady tune,
PRs skip a little moonlit rune,
Hoppity—builds stay calm and bright.
