1.0.4c-zio1: CSS 1.0.375 / net10.0, fixes, SimpleAdmin ranks

- Target net10.0 and CounterStrikeSharp 1.0.375 (compile-only reference),
  System.Text.Json instead of Newtonsoft.Json.
- Config moves to configs/plugins/CS2-Tags/tags.json, defaulting to our
  #rank/... SimpleAdmin groups. Comments and trailing commas allowed; a bad
  file is logged and the previous tags kept.
- Scoreboard tags call SetStateChanged on m_szClan, only when changed.
- Colour tags are expanded only in config strings, not in players' names or
  messages. Empty nick_color means team colour.
- A tag with no prefix or colours leaves chat to the game; drop team_chat.
- css_tags_reload works for @css/root too and reapplies scoreboard tags;
  hot reload tags connected players. Timers stop on map change. No dead
  icon for spectators.
- Remove css_tag_mute/unmute and "@" team admin chat: CS2-SimpleAdmin does
  both, and its catch-all command listener runs before these.
- Add release.sh, drop the .sln and GitHub workflow, README for the fork.
