feat: make chat a window onto her whole inner life (continuity)

Brian's felt disconnect: chat, thoughts, journal, reflections read as separate
streams. This ties them together at the chat surface.

- chat._inner_life_note(): one coherent block combining her active thought threads
  AND what she's written in her journal lately, so she carries her continuous inner
  life into every conversation (not just a single surfaced thought). Replaces the
  standalone threads block.
- persona: inner-life section rewritten to describe the current machinery (thought
  loop / threads she returns to, journal she writes in, feeds she reads, reaching
  out to Brian) and — the key change — instruct her to let that inner life show up
  in conversation naturally, the way a friend picks up where they left off, without
  info-dumping or performing it. New self-model bullets for the thought loop + journal.

Suite 65 green, ruff clean.
