fix(ci): restrict Codecov shard uploads (#2745)
## Description

Closes #2744

Restrict each Codecov Action v5 matrix upload to its declared
`coverage-${{ matrix.shard }}.xml` report. This prevents automatic
discovery
from uploading the unsharded `coverage.xml` alongside every shard.

## Type of Change

- [x] Bug fix (non-breaking change fixes an issue)

## Changes Made

- Set Codecov Action `disable_search: true` for Python shard uploads.
- Add a CI workflow contract test that protects the explicit-report-only
setup.

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check`)
- [x] Type checking passes (`mypy headroom`) (not applicable:
workflow/test-only change)
- [x] New tests added new functionality
- [x] Manual testing performed (not applicable: GitHub Actions will
execute the workflow)

### Test Output

```text
$ uv run --with ruff ruff format --check scripts/tests/test_ci_workflow.py
1 file already formatted

$ uv run --with ruff ruff check scripts/tests/test_ci_workflow.py
All checks passed!

$ uv run --with pytest pytest scripts/tests/test_ci_workflow.py -q
2 passed
```

## Real Behavior Proof

- Environment: GitHub Actions Ubuntu runner using Python 3.12.13;
Codecov Action v5.
- Exact command / steps: Run the CI Python test matrix, which writes
`coverage-${{ matrix.shard }}.xml`, then runs the Codecov Action upload
step. Inspect the uploader's discovered/uploaded report list.
- Observed result: Before this change, raw CI logs showed the Action
explicitly uploading `coverage-2.xml` and additionally
discovering/uploading `coverage.xml`. This PR configures
`disable_search: true`; the workflow contract test confirms the explicit
report setting and search disablement. Runtime upload evidence will be
added from this draft PR's CI run.
- Not tested: Codecov's final cross-shard patch calculation; that
depends on Codecov processing the reports after CI completes.

its
workflow contract test. It does not include the unrelated Copilot
Keychain fix.
