Live robot vacuums, P1 (docs/VACUUM.md)

The base marker never moves — it is the dock. While the robot cleans, a
round pulsing puck (no badge plate) drives the plan over an affine
transform solved from vacuum-map coordinates: auto-calibration matches
the robot's room list against plan rooms by name, and a three-point
wizard covers integrations without room data. The trail rides the
integration's own path when offered (it predates the card being opened)
and a self-recorded thinned buffer otherwise, lingering ten minutes
after docking. Adapters read the Map Extractor / Tasshack / Valetudo
attribute dialects through one tolerant parser. Display only — no
commands, per the owner's decision.

vacuum.ts is pure logic under 8 new unit tests; the marker schema grew
an optional vacuum block (56 backend tests); smoke_vacuum drives 19
browser asserts including the wizard end to end.
