Performance & stability pass (issue #34 + audit)
General:
- DisableAll resets only skills active in the previous round instead of all loaded skills (~89ms -> ~5ms)
- Removed per-tick LINQ/allocations, O(1) HUD skill lookups, translation substitutions moved to load time
- ForceFullUpdate creates the network service once per broadcast; view-angle guard only skips a genuine (0,0,0) placeholder
- Debug hooks/logging only active when DebugMode is enabled (single reused writer)
- Player skill state unified to a single collection (fixes a rare disconnect race)
- Gamedata signatures resolved lazily/isolated; hardened tick/transmit paths against invalid handles
- Description HUD honours always-show / -1 duration consistently across all assignment paths
Skills:
- Jester: fixed the no-damage effect leaking after a mid-round skill change (Thief/Deactivator)
- Jackal: fixed trail entities accumulating over a round
- Falcon Eye / Third Eye / Spectator: camera state cleared on disable
Also: added missing translation keys as untranslated markers across language files.
Fixes#34
Refactored command handling to improve player and skill lookup logic, replaced some list operations with direct queries, and updated method signatures for clarity and null safety. The vote system was reworked to support more robust vote tracking, cooldowns, and localized chat messages. Language files were updated to add new vote-related translations. Various code style and nullability improvements were made throughout the plugin.
