feat(search): support platform and benchmark config filters

Add platform handling to submissions and persist a normalized value (`windows`, `linux`, `macos`) with a default of `windows` when omitted.

Extend search/index filtering to support `thread`, `platform`, `intensity`, and `durationSecs` alongside existing text/CPU token matching, and wire these params through request parsing, page data, and navigation URLs.

Update API/README docs and examples to reflect the new submission inputs and search capabilities so users can run more precise queries.feat(search): support platform and benchmark config filters
