Commit 16f323319 added a strict variant-only include rule + conflict
detector in `inventory/variants.py`, gated behind the presence of any
primary's `meta/variants.yml`. In practice the rule never paid off:
* The CI failure that motivated it (matomo's matrix transition leaving
a stale dashboard nginx vhost -> 502) is already addressed by the
nginx-purge primitive shipped in commit bfd04e4a1.
* The existing `CombinedResolver` path already implements the "any
role says true or `in group_names` -> pull" semantics via
`utils.roles.applications.services.registry.is_explicit_truth`, so
every needed service still gets pulled and services that all roles
mark False stay out of the include.
* The strict literal-equality conflict detector was a false-positive
factory: 79/80 variant-equipped primaries failed it against the
current repo state because roles legitimately disagree on `enabled`
flags for shared services.
This commit removes the entire variant-only branch and restores the
single-path planner. Round-index clamping for non-primary deps is left
exactly as before 16f323319 -- only the additions are reverted.
The file-split refactor from 16f323319 is intentionally kept; only the
`variants.py` submodule, the corresponding `test_variants.py`, and the
variant-only gate test class in `test_planner.py` are removed. The
`__init__.py` re-exports + `__all__` are pruned to match.

Two changes ship together because the variant-only matrix-deploy logic
was written into the legacy 697-line inventory.py and then re-split:
* Source package (max 240 lines per submodule, well under the 300 budget):
- spec.py DevInventorySpec + PlanEntry data types
- payload.py _resolve_variant_payloads + _bake_overrides
- legacy_resolver.py CombinedResolver fallback (default-mode path)
- variants.py strict variant-only include resolution
- planner.py plan_dev_inventory_matrix + filter_plan_to_variant
- builder.py build_dev_inventory + build_dev_inventory_matrix
- __init__.py public-API re-exports + back-compat shims
* Test package mirrors the source 1:1 with a shared _fixtures.make_spec
to avoid duplicating the DevInventorySpec defaults across files.
* New variant-only matrix mode (gated on any primary shipping
meta/variants.yml): only services whose merged variant payload pins
both enabled and shared to literal True become inventory groups;
Jinja flags never qualify (group_names does not exist yet at build
time); run_after only orders the include, never expands it;
cross-primary disagreement on a (service-key, round) raises ValueError.
Default mode (no variants.yml on any primary) keeps the legacy
CombinedResolver path untouched.
* Docs in design/{inventory,variants}.md updated to point at the new
per-submodule paths; test_nginx_vhosts.py's Test classes now also
inherit directly from unittest.TestCase so the AST-level lint in
test_all_test_files_have_tests.py picks them up (transitive base via
NginxVhostsTestBase alone is not enough).
Coverage: 458 cli unit tests, 349 utils unit tests, 99 dev-deploy tests,
all green; ruff check clean.
