Mneme v2.8.0 — renamed from Mimir

Mimir is now Mneme — same memory engine, same team, new name. The rename avoids a trademark/SEO collision with Grafana Mimir and a same-niche competitor also named Mimir.

Upgrading: fully backward compatible for one transition release.

• Every mimir_* MCP tool is also registered as mneme_* — both work.
• An existing ~/.mimir/data/mimir.db is still used automatically if mneme.db doesn't exist yet — no data migration needed.
• The Docker image keeps a mimir symlink alongside the new mneme binary.
