Add closure-run identity correlation

[briancl2]

Summary

• Adds tools/emit_closure_identity.py to emit comparable local and GitHub closure-run identity JSON fields: closure_run_id, closure_phase, closure_trigger, evidence_reuse_key, parent_command, github_run_id, and github_run_attempt.
• Wires local validation through make closure-identity / make check and adds the focused make test-closure-identity regression to tools/test_all.sh.
• Adds explicit CI and Pages closure identity steps so workflow runs expose the same correlation surface as local validation.

Issue #164 / Repo-Star Replay Context

• Follows the final repo-star replay recommendation promoted by briancl2/build-meta-analysis#589 for Issue #164.
• Targets the CustomerNewsletter AS-34 field signal from the final advisor package: CustomerNewsletter:Makefile, .github/workflows/ci.yml, .github/workflows/pages.yml.
• This is an owner-surface PR; it does not mutate BMA, create controllers, install automation, or change newsletter generation behavior.

Validation

• make test-closure-identity
• python3 /Users/briancl/repos/repo-auditor/scripts/as_signature_scan.py AS-34 /Users/briancl/repos/CustomerNewsletter -> fired=false, closure_run_identity_gap_count=0
• python3 -m py_compile tools/emit_closure_identity.py
• git diff --check
• make check -> 33 required suites passed, 20 private-fixture suites skipped
• make review -> No findings

Bounded Non-Claims

• Does not add a scheduler, queue, daemon, retry loop, background sync, hidden registry, or auto-apply behavior.
• Does not claim every remaining repo-star field signal is fixed.
• Does not change production newsletter content or publishing behavior.

Record the required HIGR documentation

AGENTS.md requires every change to complete the Document step by updating HYPOTHESES.md, LEARNINGS.md, and HANDOFF.md; this change adds a new closure identity surface and validation target without updating those ledgers. Without that hypothesis/validation/handoff record, the new workflow behavior cannot be traced through the repo’s required HIGR process.
