/**
 * Filesystem-Only ProfileSource
 *
 * A `ProfileSource` implementation that resolves profiles from FHIR
 * IG packages on disk — no database, no HTTP. Drop this in via
 * `setProfileSource(createFilesystemProfileSource(...))` to give the
 * standalone engine (CLI, `@records-fhir/validator` npm package) the
 * same profile-lookup capability the server gets from its DB-backed
 * source.
 *
 * Implements `findByUrl` only. The other ProfileSource methods (bulk
 * warmup, multi-source resolveProfile) don't apply to a pure-FS
 * deployment — the SDLoader's own bundled-profile + IG-package scan
 * already covers the bundled-warmup case, and there's no remote
 * canonical resolver to chain into.
