Perseus v1.0.7

• Fixes #277: @memory/@mimir cache fingerprints include active mimir connector configuration, so command/transport/backend config changes invalidate stale memory cache output.
• Updates Perseus defaults/docs/bootstrap to launch Mimir directly with mimir --db ... rather than legacy mimir serve --mcp.
• Bumps package/runtime metadata to 1.0.7.

Verification:

• python3 scripts/build.py --check
• Full test suite outside sandbox: 1039 passed, 1 known pytest warning.
