Enforce 100% coverage across all CI legs

The first CI run of the split showed core tests failing at 99% because
`tests/cli/run.py` and `tests/cli/waiting.py` leaked through the
`test_*.py` glob, and `register_collection` in `docket.py` was only
tested via CLI tests.

Changes:
- Add `--cov-fail-under=100` to pyproject.toml as the local default
- Scope CLI job coverage to just `cli.py`, `_cli_support.py`, and
  `tests/cli/` so 100% is achievable for that slice
- Widen coveragerc-core omit to `tests/cli/*.py` (not just `test_*.py`)
- Add `test_register_collection` to core tests
- Remove stale `.coveragerc-memory` reference in `tests/cli/run.py`
