Sync contribution-check workflow and agent from github/gh-aw

[Copilot]

Syncs contribution-check workflow and agent files with github/gh-aw main (commit cf2b312a, v0.45.4).

Changes

• Agent (.github/agents/contribution-checker.agent.md): Fixed backtick formatting in code fence example, removed trailing newline
• Workflow (workflows/contribution-check.md):
  • Added TARGET_REPOSITORY env variable for cross-repository PR checking
  • Removed frontmatter description (now handled by lock file)
  • Removed pre-agent steps section (embedded in compiled workflow)
  • Updated dispatch to reference ${{ env.TARGET_REPOSITORY }}
  • Reduced 274→172 lines
• Docs (docs/contribution-check.md): Documented TARGET_REPOSITORY variable, removed obsolete configuration references

Cross-repository support

The workflow can now check PRs in a different repository:

env:
  TARGET_REPOSITORY: ${{ vars.TARGET_REPOSITORY || github.repository }}

Set TARGET_REPOSITORY as a repository variable to evaluate PRs from another repository while posting reports in the workflow's repository.

Both .github/agents/contribution-checker.agent.md and workflows/contribution-check.md now match github/gh-aw exactly (verified via MD5 checksums).

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
