kevinveenbirkenbachandClaude Opus 4.8 2f9a54cea7 fix(deploy): honor variants in include resolution
Inventory include sets ignored the active variant: swarm
derive_includes walked the variant-free base config (dynamic service
flags count as enabled) and the compose CombinedResolver followed
run_after as an include edge. Providers a variant pins to false
(e.g. mobilizon variant 1 sso) were still deployed.

- derive_includes: swap every app listed in INFINITO_APP_VARIANTS to
  its variant config, index 0 included (nextcloud variant 0 disables
  11 partner services)
- CombinedResolver: follow_run_after flag; include resolution passes
  False so run_after stays a pure ordering hint
- drop dead deps.py chain (resolve_deploy_ids_for_*) and unused
  resolve_with_edges; rewiring them would resurrect variant-blind
  run_after-following includes
- inventory.md: document the real include pipeline and
  is_explicit_truth semantics

"""Default (non-variant) include resolution for the matrix planner.
When NO primary app ships a `meta/variants.yml`, the planner falls back
to this path — the `CombinedResolver` walks `dependencies` and
`shared:`-edges in the variant-merged services map and Jinja flags are
evaluated at deploy time against `group_names`. `run_after` is NOT
followed for inclusion (it is a pure ordering hint), so a variant that
disables a service does not get the provider re-added through the
ordering edge. This module owns the two helpers that path needs and
nothing else; the variant-only path lives in `.variants`.

Apps in `primary_app_variants` use the supplied (already clamped)
index. Other roles with their own variants clamp `round_index` to
their own variant count. Roles without variants are absent from the
result so the resolver falls through to its disk-read path.
The merged map is what the inventory ALSO bakes into host_vars, so
feeding the same dict into `CombinedResolver(services_overrides=...)`
eliminates the topology-vs-host_vars drift that variant-blind
resolution produced.
