 * While a match is flagged live this plugin blocks disruptive client commands:
 * it rate-limits the radio, stops dead players from using team chat (anti-ghost),
 * blocks a small list of third-party / +hook style commands, and refuses buy
 * commands once the buy time is over. Toggle the live state with amx_matchlive.
