Three things about .keymanrc.json.
`z.object` strips a key it does not know, so `{"vaultroot": "…"}` was
indistinguishable from an empty file: the vault stayed at the default and
nothing said why. Now warned per file, listing the known keys, because for a
casing slip naming the alternatives is most of the help. Warned rather than
fatal — this module degrades to defaults throughout — and warned inside the
per-file loop, the only place the filename exists: z.strictObject on the
merged result cannot say which file said it. The known-key list is derived
from the schema shape, so it cannot drift.
`--print-config` now includes `configFiles`, in merge order. That was the one
question it could not answer, and it existed only as unstructured stderr from
loadConfig — the wrong half of the output for it. Assembled in
describeConfig() rather than in cli.ts, which is excluded from coverage.
And the `resolution` machinery is gone: roughly 45 lines that could not change
an outcome, because every schema property is a string and both strategies
return the child's value for primitives. Its one test passed either way.
mergeConfigs is now a spread. The divergence from nopy, where the same
machinery is load-bearing, is recorded in the comment above it.
