BotServ kickers: FLOOD and REPEAT

KICK <#channel> FLOOD ON [lines [secs]] kicks a user who sends too many
lines too fast (default 6 in 10s); KICK <#channel> REPEAT ON [times]
kicks one who repeats the same line (default 3, case-insensitive).

These are stateful, so the engine keeps per-channel/per-user counters in
an ephemeral map that is never event-logged. Hot-path conscious: a channel
with no kickers costs one lookup and returns; a returning speaker allocates
nothing (get_mut, not entry); repeat comparison is an allocation-free
case-folding 64-bit hash. Counters are dropped when a user parts or quits,
so the map stays bounded. Flood time is injectable for deterministic tests.
