fix(terminal): #555 landing fixes

Comment and doc corrections that #555 made stale, no behaviour change.

- stock.ts: the grok and omp altScreen comments compared their strip to
  opencode's, which is now strip-mux-and-mouse rather than the narrow
  strip. Grok now says it shares antigravity's strip until measured, and
  omp drops opencode from its comparison.
- terminal-ui.js: the touch-tap comment named Claude/Codex/Gemini as the
  stripped modes, but the gate is now the cliMouseTracking flag alone and
  covers opencode too, so it names the two stripping flavours instead.
- src/types/session.ts: the cliMouseTracking JSDoc (the flag the browser
  now gates on exclusively) listed only claude/codex/gemini; it now names
  the strip-full and strip-mux-and-mouse modes, including opencode under
  tmux.
- src/session.ts: the usesMux getter doc now names isMuxMouseStripMode,
  since the replay strip passes usesMux to it as well.
- docs/architecture-invariants.md: the narrow-strip list gains
  grok/deepseek/omp (matching the PR's own CLAUDE.md line), the
  "must REMEMBER" heading covers both DECSET-stripping flavours, and the
  cliMouseTracking writer is described as the full-or-mouse branch it
  really is.
- docs/wiki/The-Dashboard.md: the user manual said every non-Claude CLI
  scrolls locally; opencode's wheel and swipes now page its conversation.
