Replaces string-based version lookup (_normalize_mc_version +
get_version_by_name) with Endstone's integer protocol_version API,
fixing detection on unlisted hotfix releases (e.g. 1.26.11).
Extracts EndweaveMetrics to its own module.

- Add LevelSoundEvent IntEnum (570+ entries from BDS headers) with
  version-specific UNDEFINED_V860/V898/V924/V944 aliases
- Add ActorDataIDs IntEnum from BDS headers
- Fix heartbeat ActorData key (was 127/PLAYER_LAST_DEATH_POS, now
  correctly 126/HEARTBEAT_SOUND_EVENT) in v860/v898/v924 protocols
- Fix v898->v860 sound fallback returning out-of-range ID 578 instead
  of v860 Undefined (566)
- Add missing v898->v924 sound remap (v898 Undefined was incorrectly
  mapping to SaddleInWater)
- Replace all magic numbers with enum constants
- Add tests for all 6 remap directions (24 total)

Version-parameterized Type with read/write for the full LevelSettings
struct (Seed through DisablePlayerInteractions). Three variants handle
encoding differences:
- LEVEL_SETTINGS_V860: UVAR_INT DefaultSpawn Y, EXPERIMENTS_V860
- LEVEL_SETTINGS_V924: UVAR_INT DefaultSpawn Y, EXPERIMENTS
- LEVEL_SETTINGS_V944: VAR_INT DefaultSpawn Y, EXPERIMENTS

All 6 start_game handlers now use passthrough/map instead of ~40
individual field calls. Also fixes override_force_experimental encoding
to use OptionalType(BOOL) consistently per BDS headers.

- Remove _E = enum.IntEnum alias, inline type[enum.IntEnum]
- Fix override_force_experimental type annotation (Any -> bool | None)
- Extract _RULE_VALUE_TYPES dict to deduplicate GameRules read/write
- Parameterize _ExperimentsType with count_type instead of two classes
- Add section comments to all protocol.py files
- Add docstring to v898_to_v860 text handler reexport
- Convert plugin protocol registration to loop
- Add tests/conftest.py with shared fixtures
- Add "W" (warnings) to ruff lint config
- Add [tool.pytest.ini_options] to pyproject.toml
