Summary

Brings RoborockDockTypeCode and RoborockDockFeatures in line with the dock table (DockConfigs) of the newest Roborock app V1 plugins.

• New dock type codes f1rc_dock = 48 and f2rs_dock = 50. Until now these codes fell back to unknown, so the dock counted as missing and no dock traits were offered.
• Capabilities for codes 48, 49 and 50 (F1RC, F1RS, F2RS): collect, wash and dry, high-temperature water, double serial communication, simple wash modes, no-water-flow carousel (49, 50), carousel self-clean (48 without AM) and water up/down drain (AM variants of 49 and 50).
• Aliases with the app's dock names for two placeholder members: shell_4_dock (27) and f1rs_dock (49). type_27_dock and type_49_dock stay the canonical names, so .name, keys() and existing code are unchanged.
• New dock properties:
  • is_no_support_hot_wash_towel (Shell E): the app disables hot mop washing for this dock even when the robot reports it.
  • is_multi_clean_fluid_supported (Shell 4S without AM).
  • is_clean_carousel_supported (dock has a carousel/strainer).
• Docs: new "Dock Features" section in docs/V1_DEVICE_FEATURES.md. It explains that the app's "A"/"AM" variants (Shell 2SA, O5AM, ...) are not separate codes: they report the same dock_type and differ by Status.has_am.

Changed existing values

These results change for docks the library already knew. Each follows the newest app plugins.

Dock	Capability	Before	After	Source
F2R (43)	is_clean_carousel_self_clean_supported	True	False	The newest plugins no longer set carousel self-clean for F2R. Older plugins did.
K1S (20), without AM	is_clean_fluid_auto_delivery_supported	False	True	Newest plugins only (they add automatic fluid delivery to K1S). The AM variant was already True.
Hera (24)	is_hatch_door_dock_cool_fan_supported	False	True	Every plugin that knows Hera checks Couple or Hera.

Known difference, not changed here

is_special_support_wash_temp is True only for the Shell 2E Lite dock. The app's check of the same name also depends on the product: it is true for every product except PearlEPro, which needs a Shell 2E Lite dock. The library does not use this property yet. It will be fixed when the wash temperature options start using it.

Testing

• Table-driven tests in tests/test_supported_features.py for each new code and changed value, with and without AM, and for the aliases.
• pre-commit run --all-files and the full pytest suite pass.
