feat(api): support optional systemInfo in submissions

Extend the submission contract to accept a `systemInfo` object and persist it with each submission, including deep-copy support for `extra` metadata. Also update client-facing docs and HTTP examples (JSON and multipart) and document that the schema is available at `GET /api/schema`, so clients can reliably implement the updated payload format.feat(api): support optional systemInfo in submissions Extend the submission contract to accept a `systemInfo` object and persist it with each submission, including deep-copy support for `extra` metadata.

+## Notes
+
+- `systemInfo` is optional. Older clients do not need to send it.
+- The server may enrich stored analytics with request metadata such as `ipAddress`, `forwardedFor`, `userAgent`, and `locale`.
+- `baseClockMHz` and related CPU clock fields currently expect integer MHz values.
+- Full JSON Schema is available in [submit-schema.json](./submit-schema.json) and is served by `GET /api/schema`.

Daniel Legt	c8323d1b6a	feat(search): add configurable sorting for submission results All checks were successful Build and Publish Docker Image / deploy (push) Successful in 1m17s Details Introduce a `sort` query parameter in submission search paths and pass it into store search logic. Matching results can now be ordered by `newest`, `oldest`, `score_desc`, `score_asc`, `mops_desc`, or `mops_asc`, with invalid values safely defaulting to `newest`. Update README and HTTP examples to document the new sort behavior and usage so clients can control result ordering server-side without extra post-processing.feat(search): add configurable sorting for submission results Introduce a `sort` query parameter in submission search paths and pass it into store search logic.

Daniel Legt	64e3c1966d	feat(search): support platform and benchmark config filters Some checks failed Build and Publish Docker Image / deploy (push) Failing after 1m2s Details 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 Add platform handling to submissions and persist a normalized value (`windows`, `linux`, `macos`) with a default of `windows` when omitted.

This ensures image builds can run on runners where Docker is not preinstalled.ci(workflow): install Docker before Docker image build Replace the Docker availability check with an installation step in the docker publish workflow.
