Rewrite dashboard v2: terminal-style consciousness monitor

- Left panel (65%): Conscious Mind stream — each cycle shows INPUT,
  SYSTEM PROMPT (collapsible), CONVERSATION, and full LLM RESPONSE
  with model name and confidence. Auto-scrolls, scroll-lock on manual scroll.
- Right top (35%): Attention Queue — full text of all competing candidates
  with winner/loser marking and salience scores.
- Right bottom: Memory Search — debounced semantic search via search_hybrid
  (mutate=False), click-to-expand inline detail. Latest 10 on load.
- Header bar: all stats compressed into 28px (gut, bootstrap, cost, esc, queue, mem)
- New SSE event: context_assembled (full system prompt + conversation)
- Expanded cycle_start: includes all candidates with full content
- Removed all content truncation from SSE events
- Consciousness log: persistent NDJSON at ~/.agent/logs/consciousness.ndjson
