v3.0.1

Fixed

smem doctor carried two checks left over from the SQLite backend removal
in 3.0.0 that no longer served any purpose:

• Schema version — could only ever return SKIP for both remaining
  storage backends. SurrealDB applies its schema idempotently on every
  start with no stored version marker to compare against, so there was
  nothing left for this check to verify. Removed.
• Brain database — fell through to a dead .db-file existence check
  left over from SQLite that no longer applies to any valid backend. It
  now does a real check: looks up the configured brain in SurrealDB and
  reports whether it actually exists, instead of unconditionally skipping.

Both permanently capped the smem doctor summary below 100% on a fully
healthy 3.0.0 install (16/18) even though nothing was wrong. A clean
install now reports the genuine check count with real signal on both.

Upgrade

pipx upgrade surreal-memory

No config or data migration needed — this is a diagnostics-only fix.
