* fix(freehire-search): warn when --region gets a value outside the vocabulary
freehire's contract - the openapi Regions enum and RegionValues in vocab.go -
defines a closed set: nine buckets plus none. Anything else is a stray tag, so a
region filter on us or any other country code matches a handful of postings and
reads as an empty or thin market, which is how #616 started.
search now checks the requested values (--region and the --facet regions= escape
hatch, case-insensitively) against that set and, when one falls outside it, writes
one JSON line on stderr after the results, with code REGION_VALUE_UNKNOWN. The
result count is deliberately not consulted: a broad query returns real hits under a
stray tag and the parameter is still wrong. stdout stays clean JSON, exit code 0.
Tests are unit-level with a stubbed fetch: no extra request to the free API, and no
change to the existing search tests.
* changelog: place the #651 entry under [Unreleased]
