docs: refresh Codex context contract

[saagpatel]

What

docs: refresh Codex context contract.

Why

Preserve the already-reviewed local cleanup branch from the Projects portfolio cleanup lane so the working tree can stay clean without losing context.

How

Branch contains documentation/context or local operating-surface cleanup only.

Testing

• Local git diff --check passed before commit/push.
• Final portfolio dirty scan reached dirty_count 0 before this PR creation pass.

Risks

Low for docs/context branches; operating-surface branches only adjust Codex-local inheritance/config surfaces.

Performance impact

None.

Lockfile rationale

No lockfiles changed.

Screenshots

Not applicable.

Keep inherited agent rules repo-local

When this repo is used outside the author's workstation, this absolute /Users/d/.codex/AGENTS.md reference is not available, so the explicit blocking test/docs/reviewer-loop requirements that were deleted above no longer reach Codex agents. I checked this workspace and the referenced /Users/d/.codex/... files are absent, which means a normal checkout loses the repo's Definition of Done instead of inheriting it; either keep those requirements in this file or reference a repo-tracked path.
