Makes the integration fully self-contained for HACS distribution.
Users installing via HACS get everything in one directory; no external
samsung_appliance package needed.
All component imports updated to relative (.ocf.*); all test imports
updated to custom_components.localthings.ocf.*. ocf_root_ca.pem moves
with the package and resolves correctly via Path(__file__).parent.
Remove key_fn from Capability — pattern cap keys are now always derived
automatically: strip digits from href segments, join with '_', append
'_' + desc.key. /door/cooler/0 + 'open' -> door_cooler_open.
DOOR_GENERIC entity key: 'open' (not 'door_open'). Remove _door_key helper.
Fridge registry: DOOR_FRIDGE/DOOR_FREEZER replaced by DOOR_GENERIC pattern cap.
Golden baseline: door_fridge_open -> door_cooler_open.
Move device dumps to tests/fixtures/dumps/ (tracked) so tests run in CI
without local-tools/ dependencies.
Registry changes from dict[str,Capability] to dict[str,list[Capability]].
discover() gains pattern_caps parameter (fallback for unmatched hrefs)
and gates each candidate on rt_filter and match_fn before binding.
Duplicate hrefs in registry allowed only if all caps set a discriminator.
OCF rt is a schema category shared by many unrelated resources.
The stable unique resource address is the href. Update Capability,
discovery, common capabilities, tests, and plan accordingly.
Implement discovery module for converting OCF resource metadata into bound
entities, with support for multi-instance device resources and logging of
unknown capabilities.
