* docs(jobindex-search): align search examples with the actual CLI contract
The posted-today skill example omits the query that the shipped CLI requires, so copying it exits MISSING_REQUIRED. Supply a keyword and make the required flag explicit. Replace stale JSON-endpoint/card-parser search documentation with the implemented HTML Stash route and emitted field behavior.
Run the example read directly from SKILL.md through a real CLI subprocess with loopback HTTP fixtures. Keep a separate query/page routing control; no live portal requests or production-code changes.
* test(jobindex-search): cover Windows documentation newlines
