fix(website): correct false claims and stale numbers in live docs

- Landing: replace nonexistent `mempalace remember` CLI demo with real
  `mempalace mine ./notes`
- Landing: soften unverifiable absolutes ("forever available",
  "100% recall by design", "<50 ms", "90%+ compression",
  "two-thousand-year-old", "tens of thousands of entries")
- MCP tool count: 19 → 29 across mcp-integration, claude-code, openclaw,
  and modules; expand tool overview with Drawers, Tunnels, and System
  categories to match mcp_server.py
- Wake-up token range: ~170–900 → ~600–900 in cli/api-reference/python-api
  to match cli.py help text and concept docs
- Gemini CLI: move `--scope user` before target name and add `--`
  separator so `-m mempalace.mcp_server` isn't parsed as Gemini flags
