Log Message:
chat_llm: IRC bot acknowledges brief replies to its own lines

When a user makes a clear, brief, *unaddressed* reply to the bot's OWN
last line, the bot now reacts once with a short in-character line (bare,
no nick prefix).  Three cases:

- closer    -- a social acknowledgement ("ah ok", "thanks", "makes sense")
- correction-- pushback ("no, that's wrong") -> a gracious concession that
              never re-asserts or argues
- answer    -- the bot's last line was a question and the user answered it
              -> a brief reaction that doesn't ask a new question or start
              a new topic (so it acknowledges without restarting the volley)

Deterministic gate (chat_llm_irc.js handle_privmsg): the bot's prior line
must be substantive (a reply/intervention, never another ack) + recent +
directed at this speaker with nobody in between, the speaker not muted, a
per-channel cooldown elapsed, and the text matches a closer/correction
shape (ack_kind) -- or, for 'answer', our prior line ended in '?'.  Closers
are probabilistic (irc_ack_closer_chance, default 0.9); corrections and
answers always react.  The bot never reacts twice in a row, so the user
always gets the last word.  ack_kind + chat_llm_ack live in chat_llm.js
(classifier is unit-testable; the line is a constrained model call with a
canned fallback on ramble/question/error).

New config (chat_llm.ini, default ON): irc_ack_enabled, irc_ack_window,
irc_ack_cooldown, irc_ack_closer_chance -- documented in the module header.

Also carries the irc_intervention_min_tokens gate (default 2): an
unanswered question must have at least N content tokens to qualify for a
high-confidence unprompted intervention, so a single content word can't
carry a "confident enough to chime in" score.
