feat: thought loop closer to her vision — wander grist, continuity, seeding, lifecycle

Four additions so the loop is "more what she wanted" (think to herself, unprompted):

- Wander grist (#1): think() new-thread mode now draws the same varied seeds
  reflect() uses (self_state.wander_seed: own curiosity/existence/disagreement or
  a resurfaced memory) + an anti-restate block of her recent thoughts + a list of
  existing open-thread titles to avoid. Directly counters the RLHF "supportive
  presence serving Brian" drift visible in her first thoughts.
- Continuity: thoughts.context_note() injects her active threads into every chat
  turn, so she's aware of her own ongoing mind and can reference it anytime — not
  only when a thought crosses the surface bar.
- Bidirectional: new think_about tool (in _BASE, all modes) lets her spawn a
  thread from conversation to develop on her own later. Conversations seed her
  solo thinking.
- Lifecycle: thoughts.decay() rests stale active threads (>48h) and decays their
  salience, sparing pending-response ones; runs each dream cycle (no LLM). Frees
  the open-thread cap and keeps the feed current.

Also: thoughts feed no longer wipes a reply you're mid-composing (skip poll
re-render while a textarea is focused/non-empty; force-refresh after send).

61 tests passing, ruff clean.
