docs: reposition tagline to lead with use cases, keep SQLite as explanation

Old: "The SQLite of bi-temporal graph databases"
New: "Embedded graph memory for AI agents, mobile apps, and the browser —
      the SQLite of bi-temporal graph databases"

Updated in README.md (header, Why Minigraf table caption, comparison
footer), PHILOSOPHY.md (opening and unique-positioning lines),
ROADMAP.md (philosophy line), and CLAUDE.md (project overview).

The SQLite philosophy and inspiration are preserved throughout — the
framing shifts from "what it is" to "what it enables", with the SQLite
comparison as the credibility anchor rather than the lead.
