policy: foreign-exceptions.txt is missing the pre-rule files modified by label-gated PRs #6826/#6847 #6936

What

tools/policy/foreign-exceptions.txt has no entries for four pre-rule foreign files that recent label-gated PRs modified:

• .github/workflows/auto-merge-ready-prs.yml, tools/bees/merger_gate_selftest.py -- fix(merger): judge red checks the bee answered for, run on the bee's label, read every bee-reviewed PR #6826 (merger)
• .github/workflows/queen-export-push.yml, tools/queen/export_push.py -- fix(queen): export-push pushes what it can, accepted heads first; accepted newer attempt replaces an older unpublished tip (Refs #6657) #6847 (queen export-push, Refs P0: Queen Scheduler Control Layer — dispatch, leases, manual Bee control #6657)

Why it bites

Lefthook own-language checks a local merge-commit against its first parent, so merging master into any branch now trips on these four files even though the branch itself adds no foreign code. Hit while running the conflicts-rebase route for #6695; same mechanism as the #5921 trap, now triggered by master-side content.

CI is not affected (it reads the BASE copy of the exceptions file, and the PRs that modified these files carried the owner-approved-foreign label); only the local merge-commit route is.

Done when

The four paths are recorded in tools/policy/foreign-exceptions.txt and a merge of origin/master into a feature branch commits cleanly under lefthook.
