Marc Billow daf7e3787f Add ruff (lint + format) and ty (type checking) to the project
Adds [tool.ruff] and [tool.ty] config to pyproject.toml with a curated
ruff rule set (E, F, W, I, UP, B, C4, SIM, RUF, ASYNC, LOG, G, PIE, RET,
PERF, N), pins ruff/ty in requirements-dev.txt, reformats the whole tree
with `ruff format`, and fixes the pre-existing lint and type-check debt
those tools surfaced so both run clean.

Production-code type fixes include: HA's ConfigFlowResult vs. the
generic FlowResult in config_flow.py, narrowing BoundEntity.desc to its
platform-specific subclass (SelectDesc/NumberDesc/SensorDesc/etc.) via
cast() instead of an unchecked annotation, converting HA device_class
strings to their proper enum types, a resolve_registry callback typed
as `object` instead of `DeviceRegistry | None`, and a couple of other
narrow correctness fixes (CA key type validation, an index-out-of-bounds
false positive from an empty-tuple fallback, a bool/dict argument swap).

Test-file fixes are mechanical: narrowing SamsungEntityDescription to
the correct subclass via isinstance()/cast() before accessing
subclass-only fields, and asserting Optional write_fn/unit_fn fields
are set before calling them.

"""Tests for the /mode/vs/0 match_fn discriminator in capabilities/
air_purifier.py (issue #130).
`_has_top_level_modes` decides whether a given air-purifier dump's shared
/mode/vs/0 href binds to the older ARTIK051_TVTL family's MODE capability
(packed options[] scheme) or the newer TP1X_DA-AC-AIR family's FAN
capability (modes/supportedModes reported directly). Pure function, no
coordinator/entity dependency needed to test it directly -- same rationale
as test_climate_wind_oscillation_fallback.py's `_oscillation_swing`.
