fix(wrap): keep Codex RTK guidance global (#1240)
## Description

Stops `headroom wrap codex` from writing RTK instructions into the
shared project `AGENTS.md`. RTK guidance remains installed in the global
Codex `AGENTS.md`, where it applies only to the user who configured
Headroom.

Closes #1235

## Type of Change

- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- Remove project-level RTK guidance injection from `headroom wrap
codex`.
- Preserve global Codex RTK guidance injection.
- Add a regression test proving an existing project `AGENTS.md` remains
byte-for-byte unchanged.
- Document the fix in the Unreleased changelog.

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [x] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [x] Manual testing performed

### Test Output

```

## Real Behavior Proof

- Environment: Windows, Python 3.12.12, locally built Headroom CLI,
isolated project directory, isolated `CODEX_HOME`, and isolated
`HEADROOM_WORKSPACE_DIR`.
- Exact command / steps: created a project `AGENTS.md`, recorded its
SHA-256, then ran `.venv\Scripts\headroom.exe wrap codex --prepare-only
--no-mcp --no-serena` with isolated environment directories and compared
the project hash before and after.
- Observed result: command exited 0; RTK downloaded successfully; the
project `AGENTS.md` hash remained
`2CFF2F420178BFEB9BB863C743805410F2CA30F3F7F70121A8538314CBD0F8B5`; the
global Codex `AGENTS.md` was created and contained the
`headroom:rtk-instructions` marker.
- Not tested: launching an interactive Codex session after preparation;
non-Codex wrapper targets, which are unchanged.

## Additional Notes

The repository-wide pre-commit mypy hook reports existing Windows-only
`fcntl` attribute errors in `headroom/subscription/tracker.py` and
`headroom/install/runtime.py`; targeted mypy for the changed module
passes. The plugin-version hook was also verified directly with the
project interpreter and correctly skipped this feature branch.
