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.

+- Docked robot: only the base marker, at the user-placed spot. No puck.
+- Cleaning + calibrated map: a round pulsing puck (no badge plate) drives the
+  plan; the base marker never moves. Heading wedge follows angle+matrix
+  rotation; no angle attribute — no wedge.
+- Trail: integration `path` preferred, else self-recorded; lingers 10 min
+  after docking; a new run clears it; `trail: false` hides it.
+- Hidden marker: neither puck nor trail. Uncalibrated active map: no puck.
+- Wizard: 3 stage clicks with the robot parked at 3 spots → matrix saved per
+  map id; Esc cancels; collinear points are rejected with a toast.
+- Auto-calibration needs ≥3 rooms matched by name between the robot and plan.
