[q] feat(triage): restrict PR triage to fork PRs only

[github-actions]

Summary

Restricts the PR Triage Agent to only process PRs opened from forks, as requested.

Change

In Phase 1.2 (Query Open Agent PRs) of pr-triage-agent.md, added an explicit instruction to filter out PRs that originate from branches within the same repository. Only PRs where head.repo.full_name differs from base.repo.full_name (i.e., fork PRs) will be processed.

Modified File

• .github/workflows/pr-triage-agent.md — added fork filter instruction to Phase 1.2

Rationale

The triage workflow was processing all agent-created PRs regardless of origin. By limiting it to fork PRs only, same-repository branch PRs (internal development branches) are excluded from automated triage, which makes sense since those are typically managed directly by the team.

Validation

Workflow compiled successfully ✅

Note: .lock.yml file will be regenerated automatically after merge.
