CS2main

## CS2main 0.9.0-rc.3

- Reworked C4 scaling and floor placement; a killed carrier now leaves a recoverable C4 that only T players can pick up.
- Added G-to-drop and E-to-pick-up controls for weapons and C4, with aimed server-authoritative pickup.
- Restored the standard Minecraft crosshair and enabled TACZ aiming only for weapons with built-in or installed optics.
- Fixed the headshot icon and made headshot metadata survive delayed damage events.
- Added hard CT/T voice packet isolation and a HUD indicator for speaking teammates when Simple Voice Chat is installed.
- Expanded the default TACZ shop with CS-style pistol, SMG, shotgun, rifle, sniper and machine-gun presets, including a suppressed USP-S preset.
- Added class-based damage caps, armor penetration and movement/kill-reward behavior for both default and administrator-added TACZ weapons.
- Added switchable `tactical` CC0 sounds and `vanilla` Minecraft sounds through `/cs config sounds tactical|vanilla`.
- Fixed TACZ magazine synchronization: every accepted shot now consumes exactly one round, blocked shots restore their round, reloads resync the magazine and purchased guns start loaded.
- Hid unfinished bot commands and release documentation.
