docs(jobindex-search): align search examples with the actual CLI contract (#579)

* 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

 - Page size is fixed at 20 results per page (Jobindex API limitation).
 - Area/region filtering via API params does not work — include city names in `--query` instead.
 - `--jobage 9999` is the default and includes all postings regardless of age.
-- Total count in `meta.total` uses Danish dot-thousands notation internally (e.g. `18.903`) — the CLI normalizes this to a plain integer.
