feat(zeo): add core ZeoApi with ZeoCommandTrait and ZeoFeatureTrait

ZeoCommandTrait (new: command.py, 165 lines)
- start_program: bundles start params via FIELD_TO_DP, QoS 1
- pause / resume / shutdown: single-DP commands
- Start param sets split by device type (washer 10 DPs, dryer 7 DPs)
- Feature-gated DPs conditionally included from cache
- Dependencies injected: channel, dps_cache, feature_trait, proto_entries

ZeoFeatureTrait (new: device_features.py, 185 lines)
- ZeoFeatures dataclass (24 bool flags): from_feature_bits() via name reflection
- Product type detection: static model ID whitelists (dryer/Hyperion/M1)
- is_dryer / is_hyperion_halia_hera / is_m1_muse_metis — no device query
- refresh(): query DP 237 once, cache in memory

ZeoStartParams (zeo_containers.py): expanded to 13 fields covering washer + dryer
ZEO_PROTOCOL_ENTRIES (__init__.py): expanded to ~69 DP-type mappings
RoborockZeoProtocol: add UNKNOWN_246, UNKNOWN_259 placeholders

Builds on #895 (MQTT push subscription).
