fix(project): a module resref names a file, not a resource (#93)

Browse Source 
`module.resref` is the name of the built `.mod` on disk, so the 16-byte resref limit never applied to it — NWN:EE module file names are routinely longer. The blanket check rejected `ShadowsOverWestgate` (19 characters) and blocked sow-module#60:

```
crucible module build
  module.resref "ShadowsOverWestgate" exceeds 16 characters
```

## What changed

`internal/project/project.go` — `module.resref` is validated as a **file name** now, which still rejects a resref that is a path or empty.

The 16-character limit is kept where the value really does become a resref: a project with `paths.assets` and no `haks[]` names its single generated HAK after the module resref (`build.go:1144`), and a HAK name is a resref the engine loads. That case now says what to do about it instead of refusing every long module name.

## Verified

- 3 new tests in `internal/project`: a long module name validates and produces `ShadowsOverWestgate.mod`; a resref containing a path is rejected; a long resref that would name a generated HAK is still rejected.
- `make check` green.
- `crucible module build` in sow-module writes `module/ShadowsOverWestgate.mod` (70 resources).
- `crucible topdata validate` in sow-topdata still passes — its assets live under `topdata.assets`, not `paths.assets`, so the HAK guard does not bite.

Merge this **first**: sow-module's rename PR cannot go green in CI until this lands and its `flake.lock` is bumped.
