The DTLS/CoAP transport code that made "ocf" an accurate name moved out to
the smartthings-local package. What's left here (capability.py, entities.py,
discovery.py, adapter.py, identity.py, capabilities/, by_type/, plus the
/device/0 batch parser) is entirely the device capability registry, so name
the package for what it does.
Flattened the redundant ocf/registry/ nesting into a single top-level
registry/ package and updated every import across the platform modules and
test suite accordingly. Verified: full test suite (80/80) passes, and the
Docker dev container reconnects to both live appliances and rediscovers
their entities cleanly after the rename.
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.
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.
