Migrate the simple `PROJECT_ROOT = Path(__file__).resolve().parents[N]`
shape across the repo to the new "import from `__init__.py`" rule
introduced by the `project-root-import` lint:
- `utils/cache/__init__.py` is the canonical source. `PROJECT_ROOT`
and `ROLES_DIR` move out of `utils/cache/base.py`; `base.py`
re-exports them for callers that still import from there.
Internal cache modules (`files.py`, `gitignore.py`) switch to
`from . import PROJECT_ROOT`.
- 24 packages receive a `PROJECT_ROOT` declaration in their own
`__init__.py`, each with the parents[N] depth that resolves to
the repo root.
- ~36 consumer files swap their local
`PROJECT_ROOT = Path(__file__).resolve().parents[N]` for
`from . import PROJECT_ROOT`. `ROLES_DIR` and similar derived
paths stay local (`PROJECT_ROOT / "roles"`).
Status: this commit closes the simple-shape violations. The
multi-line `os.path.abspath(os.path.join(here, os.pardir, …))`
shape, `def repo_root()` while-loops, and `roles/<role>/filter_plugins`
files without a package container remain. The lint stays scharf and
will track each subsequent wave.

Both in-process cache layers — the cached YAML loader and the cached
runtime-data getters — now live next to each other under
`utils/cache/`. The package gains a README that documents the
"orthogonal layers, no third cache" rule so future contributors hit
the right primitive on the first look.
Moves:
- `utils/yaml_cache.py` -> `utils/cache/yaml.py`
- `utils/runtime_data.py` -> `utils/cache/data.py`
- `tests/unit/utils/test_yaml_cache.py` -> `tests/unit/utils/cache/test_yaml.py`
- `tests/unit/utils/test_runtime_data.py` -> `tests/unit/utils/cache/test_data.py`
- `tests/unit/utils/test_variants.py` -> `tests/unit/utils/cache/test_variants.py`
New:
- `utils/cache/__init__.py` (empty per project convention)
- `utils/cache/README.md` describing the two layers, when to reach for
which, lifetime, test-only helpers, and design guidelines (RFC 2119
keywords, emoji-after-headline, no self-SPOT declaration, no
slash-in-link-text).
- `tests/unit/utils/cache/__init__.py`
Mechanical updates:
- All imports across cli/, plugins/lookup/, tests/, and roles/ rewritten
from `utils.yaml_cache` -> `utils.cache.yaml` and
`utils.runtime_data` -> `utils.cache.data` (40+ files).
- `REPO_ROOT` parents-index in the moved tests bumped from `parents[3]`
to `parents[4]` to reflect the deeper nesting.
- Six broken markdown links in docs/ updated to the new module paths
(test_markdown_links lint test stays green).
- Two test files that used the `from utils import runtime_data` form
now use `from utils.cache import data as runtime_data` so the local
alias remains.
Tests: 848 passed across unit + lint suites (1 pre-existing collection
error in test_host_vars.py unrelated to this change).
