Bridge canonical personal sync generation

[JoeyTeng]

Note

This PR is purely generated by LLM: OpenAI Codex (GPT-5.6 Sol (reasoning xhigh, summaries auto)).

Summary

• declare codex-personal-sync as the canonical owner of generated sync sources
• make toolbox CI and release validation discover all current and future test modules
• include generated schema and provenance-receipt changes in release workflow triggers
• add a compact consumer contract test and workstream journal

Current phase

This draft currently contains only the signed consumer-wiring checkpoint. It
does not copy unpublished canonical engine, schema, test, lock, or receipt
bytes. After Joey-Tools/codex-personal-sync PR #5 lands, a second append-only
signed commit will be generated from that exact committed merge tree.

Validation

• Python 3.13.0: python3 -B -m unittest discover -s tests — 775 passed
• Python 3.9.6: python3 -B -m unittest discover -s tests -b — 775 passed
• Python 3.13 and 3.9 focused consumer contract — 4 passed on each runtime
• python3 -m compileall -q scripts tests
• Python 3.9 compileall with a task-scoped bytecode cache
• ruff check scripts tests
• ruff format --check tests/test_generated_mirror_consumer_contract.py
• actionlint for all three workflows
• project journal validation
• git diff --check

Follow-up gate

• regenerate the final toolbox mirror from the exact landed canonical SHA
• prove generator idempotence, receipt/file/mode/digest parity, and source lock freshness
• rerun both runtimes, admission, CI, and a fresh whole-range named single review
• leave merge and GitHub Codex request to the coordinating workstream
