A search that ignores what a thing is called is no search, so the name wins (#43)

Typing "variable" into the node palette landed on `Run behavior`, because the
filter weighed label, type and description alike and then sorted by category.
`searchRank` in `src/ui/search.ts` now ranks a match: exact label or type, then
prefix, then label, then type, and only last a hit that lives in the
description alone. Category and alphabet order within a rank. The searchable
`Menu` uses the same function, so searching means the same thing everywhere.

The `+` menu grew to fifteen entries in declaration order. It is built in two
alphabetical groups now -- the types that go into a scene, then the ones that
stay in the library -- with a separator between them, the split `isPlaceableType`
already draws. `ASSET_TYPES` itself stays untouched: it is also the
serialisation and check order. A search flattens the groups and drops the lines.

Popups were capped at fixed heights (320 menu, 260 palette, 340 pickers) while
the canvas had room to spare. `Popup.roomFor()` measures its own chrome and
takes the window height minus a tenth at each end. Placement clamps
asymmetrically: the bottom margin is enforced, the top is only a budget, so a
menu anchored near the top stays at its button instead of being pushed off it.
