Barrett Ruth e9f72dfbbc feat(cses): implement submit via REST API (#299) ... ## Problem CSES submit was a stub returning "not yet implemented". ## Solution Authenticate via web login + API token bridge (POST `/login` form, then POST `/api/login` and confirm the auth page), submit source to `/api/courses/problemset/submissions` with base64-encoded content, and poll for verdict. Uses the same username/password credential model as AtCoder — no browser dependencies needed. Tested end-to-end with a real CSES account (verdict: `ACCEPTED`). Also updates `scraper.lua` to pass the full ndjson event object to `on_status` and handle `credentials` events for future platform use.		2026-03-05 01:07:57 -05:00
