skill: cross-module types priced, and the price was zero

[gHashTag]

Closes #3351

The Rust emitter drops every use line, so a type declared in a sibling spec is undefined in the generated file. Twelve specs fail that way, six of them on Trit. It is worth nothing, and three measurements say so in increasing order of finality.

1. Of the twelve, eleven carry between 9 and 84 other errors. Only ternary/bigint.t27 fails on missing types alone.

2. Of 55 types imported by name across 46 specs: 18 declared exactly once, 8 declared in 2–4 places, 29 declared nowhere at all. Trit has four declarations, and a module index does not save it — two files declare module tritype and both declare Trit. They agree by luck.

3, the one that settles it. Pasting the real definition into the single unblocked spec's generated Rust by hand:

bigint.t27 without the definition   5 errors
bigint.t27 with it pasted in        4 errors   (3 mismatched types remain)

A resolver — new file I/O, a module index, recursion guards, ~100 lines — moves the corpus by zero.

The method is the lesson: satisfy the dependency by hand before building the machinery that would satisfy it. One command priced a hundred-line feature at nothing.

Includes a correction to my own earlier note, which said Trit is declared in exactly one spec — that came from grepping type Trit only; with the full matcher it is four.
