fix(bridge): Armada launches into the catalog viz, not a dir listing

Clicking L'Armada served armada/ root → a file listing (felt broken). Point it
at armada/tide-table (where the viz lives) and open /triangle.html — same as
`tide.py serve`. Verified: /triangle.html → 200.

Also lands midimon.enrich() (note/velocity/controller→structured) + tests, the
parsing groundwork for the live MIDI dashboard panel.
