Function diffManifest

diffManifest(
manifest: unknown,
declared: DeclaredContributions,
): readonly ManifestMismatch[]
Every disagreement between package.json and the declarations in src, as data, in the order the checks run: commands, then settings, then views.

The same comparison assertManifestMatches makes, without the throw — for a tool that wants to print, count or apply the mechanical part of the fix itself. An empty result means the two agree on everything this checks.
Parameters
- manifest: unknown
- declared: DeclaredContributions
Returns readonly ManifestMismatch[]
Example
```
const mismatches = diffManifest(manifest, { commands: Object.values(Contracts) });
for (const mismatch of mismatches.filter((m) => m.direction === 'missing-in-manifest')) {
  console.log(mismatch.paste ?? mismatch.summary);
}
```
