docs: record the filed Codex feature request in the patch record

[novelKR]

Records the Codex feature request for the recorded patch from #93 in the patch record. The request was filed on 2026-10-12, with the owner's approval, as openai/codex#53298.

Issue

Scope: the patch record's Upstream row, which the patch policy (docs/upstream-patches.md) keeps current. Tracked in #76 and novelKR/DevGuard#14. This PR does not close an issue.

Item	Value
Base	main at 181a020 (#95's merge)
Head	7727d24
Pins	Codex gitlink 6b9826e3 with the recorded patch (tree 19999371), DevGuard 6e7e065; both unchanged

Summary

The patch policy proposes each patch's capability to Codex as a feature request and keeps the request's status in the patch record. Until now the record said the request was drafted and not submitted.

• docs/upstream-lock.md, docs/ko/upstream-lock.md: the downstream patch record's Upstream row links codex-utils-pty: let a caller observe an exited PTY child before the waiter reaps it openai/codex#53298, filed on 2026-10-12 with the owner's approval.
• docs/translations.json: the upstream-lock hashes, recorded with scripts/check_docs.py record --id upstream-lock.

Contract changes

None. scripts/codex_patch.py reads only the Patch and Patched tree rows of this table, and both are unchanged.

Tests

Verified locally at 7727d24:

• python3 -B scripts/check_docs.py: 18 paired documents verified.
• python3 -B -m unittest discover -s scripts/tests -p 'test_*.py': 65 tests passed.
• codex_patch.read_record() still reads the pinned commit 6b9826e3, the patch's SHA-256 6f615798 and the patched tree 19999371.
• git diff --check origin/main HEAD: clean.
• python3 scripts/ci_plan.py --base origin/main --head HEAD: profile full, because docs/upstream-lock.md is the pin record, so CI runs every leg.

The Rust legs were not run locally.

CI on 7727d24: CI run 38217515124 passed all 17 jobs: plan, format and pin, policy scan, the three clippy legs, the seven unit legs, Linux isolation, integration, macOS contracts, and the rust summary. Documentation site run 38217516078 passed.

Security scenarios

Documentation only. No code, credential, path or workspace handling changes.
