feat: add afterthoughts, memory callbacks, and callback-worthy extraction

Add triple-pipe afterthought splitting to chat replies so the bot can
send a follow-up message 2-5 seconds later, mimicking natural Discord
typing behavior. Update all 6 personality prompts with afterthought
instructions (~1 in 5 replies) and memory callback guidance so the bot
actively references what it knows about users. Enhance memory extraction
prompt to flag bold claims, contradictions, and embarrassing moments as
high-importance callback-worthy memories with a "callback" topic tag.
