fix(fs): pin path dep to a version to satisfy cargo-deny wildcard rule

cargo-deny treats `pearlite-schema = { path = "..." }` as a wildcard
dep because no version constraint is present. The workspace lints have
`wildcards = "deny"`. Pinning to "0.1" matches workspace.package.version
(0.1.0) and the workspace SemVer baseline.
