fix: Claude view parsing/scroll, ngrok warning bypass, reliable send

Claude parsed view:
- Tables now require a real column-border row (┌┬┐/├┼┤); welcome/notice boxes
  (rounded ╭╰, single │ column) no longer render as garbled tables
- Tighten code detection so log lines / prose with parentheses aren't boxed as code
- Status bar no longer eats prose/question lines containing a "·"; pull ctx%/model
  from combined statuslines
- Renderer hashes full block content, so streaming updates re-render instead of
  freezing ("parsed, then not")
- Left-normalize TUI lines shoved to the right on wide panes (text/response/tool
  output only; code/tables/diffs untouched)

Scroll history:
- Stop the loader flash-loop once scrollback is exhausted (noMoreHistory guard)
- Keep the reading position on load; older content is revealed by scrolling up
  further (preserve-position)

ngrok:
- No-cache pass-through service worker adds the ngrok-skip-browser-warning header
  to navigations so the free-tier interstitial is skipped on revisits
  (replaces the old caching SW; sw-unregister removed)

Send:
- Server awaits send_text before pressing Enter so the submit can't race the
  bracketed paste (fixes "had to press Enter twice")
