Rebuild browser WASM with the unit diagnostic

Rebuild browser WASM from the final search width engine

Start the HNSW search width at 64 and cut the width test to 6,000 x 16

Starting at 64 instead of 32 raises recall at 100k (uniform 32 dims 0.984 -> 0.995, clustered 128 dims 0.993 -> 0.998) for a little more work on easy data. The width test now runs in about 28 s in a debug build and still fails with the fixed width of 768. docs/vector.md states the guarantee by relative contrast.

Underline a misplaced 'in ' at the word itself

Declare units in the browser path test's schema

Rebuild browser WASM with units on the weight type

Declare the A* distance unit on the weight's type, not in the query

A number field takes its unit in its type: km: Float, len: Int, Float. toward reads the unit from the weight; toward on a weight with no unit is a checker error, and a unit on a non-number type is a schema error. The query's 'in ' is gone.
