Forgotten Frequency

- Fixed a Fabric startup crash in the second client run profile caused by registering the `client_music_state` server receiver before its payload type
- Kept Fabric payload registration order aligned with Fabric Networking API requirements
- Includes the 1.0.0-mc1.21.1 feature set plus the post-release Fabric launch fix

- Added Lost Broadcast music disc with item model, texture, jukebox song data, custom audio, creative tab entry, and chest loot injection
- Added new atmospheric event `unseen_hand`, replacing the old door-slam interaction with nearby doors, wooden trapdoors, fence gates, and chest lid scares
- Added `bell_ring`, which searches nearby bells and rings them as a spatial world cue
- Added `flame_falter`, which permanently extinguishes lit candles and campfires using block tags for broader vanilla compatibility
- Added `cold_breath`, spawning vanilla breath-like particles around affected players
- Added `screen_static`, with a Fabric client overlay, deterministic pixel-noise rendering, client tick timing, and a trimmed 2-second static sound synced to the visual effect
- Added `radio_numbers`, including two number-station audio variants and radio-gated playback behavior
- Added `music_cut`, which interrupts active music/records and plays a stinger only when the client reports an active music source
- Added client-to-server music state reporting so `music_cut` can avoid no-op triggers when no music is playing
- Added reroll handling for no-op atmospheric events so failed world interactions do not consume an event slot silently
- Added localized subtitles and text for all new event sounds in English, Russian, and Ukrainian
- Added new sound registrations and resource-backed audio for flame falter, cold breath, radio numbers, music cut, screen static, and Lost Broadcast
- Added server config toggles for the expanded atmospheric event set
- Added shared `AtmosphericWorldPlanner` logic in `common` so Fabric and NeoForge use the same spatial search/planning rules
- Added debug visibility for new events and no-op reroll behavior
- Isolated Fabric runtime directories by Minecraft version to make parallel 1.20.1/1.21.1 testing safer
