feat(market): hot-searches range filters, flattened params, long-form fields

- Add --min-*/--max-* range flags to `market hot-searches` (same metric names as
  market trending); flatten filter fields onto each param (no nested filter object)
- Document response as long-form RankItem fields (server maps shortcodes); drop the
  filter_id field from the documented response shape
- Sync SKILL.md, cli-usage.md, Readme.md, Readme.zh.md, and OpenApiClient types
