Log Message:
chat_llm: introduce LLM-backed chat engine with tool calling and RAG

Adds an Ollama-backed chat infrastructure for the BBS guru:

exec/chat_llm.js -- chat engine: dispatch, classifier,
tool loop, RAG injection, postprocess
exec/chat_llm_irc.js -- IRC bot adapter (joins channels, runs
chat_session on direct address or
high-confidence intervention, queues
and delivers relay messages)
exec/llm_tools.js -- tool registry: loads exec/llm_tools/*.js
and registers each via llm_tool_register
({name, execute, def})
exec/llm_tools/_common.js shared helpers
exec/llm_tools/bbs_directory.js sbbslist lookup + finger probe
exec/llm_tools/this_bbs.js local subs/libs/dirs/doors/stats
exec/llm_tools/external_archives.js curated BBS-era archive index
exec/llm_tools/relay_message.js deferred-delivery message queue
exec/llm_index.js -- RAG index builder (BM25)
exec/llm_index/dokuwiki.js DokuWiki page crawler
exec/llm_index/filebase.js file-base description crawler
exec/llm_index/msgbase.js message-base post crawler
exec/llm_external_archives.json archive data
ctrl/chat_llm.ini engine + chat config
ctrl/chat_llm_persona.utf8 system prompt, normal turns
ctrl/chat_llm_opening_persona.utf8 system prompt, opening turn
ctrl/chat_llm_greeting.utf8 user-role greeting trigger

Adding a tool = drop a file in exec/llm_tools/; the loader picks
it up automatically. Runtime files derive from <persona>_<protocol>
base (default "guru_irc") so multiple bots can coexist in data/.

The engine speaks Ollama's OpenAI-compat /api/chat endpoint; tested
against qwen2.5:7b with the Synchronet wiki + filebases as RAG sources.
