Eirel Dashboard and CLI v0.5.1 Ship

Eirel released v0.5.1 CLI and dashboard updates improving submission transparency. Leaderboard now correctly displays evaluated results without resubmission overwrites, new Submissions tab shows pending runs with clearer build/status feedback, and eager build verification provides immediate verdict at upload time. CLI `eirel status` command now displays human-readable submission history with build verdicts and failure reasons instead of raw JSON. Run 5 started.

• •Leaderboard fix prevents resubmissions after run completion from overwriting earlier results
• •Dashboard Submissions tab surfaces build_failed and received statuses; actionable error hints replace raw errors
• •CLI v0.5.1 shows submission history with build verdicts, failure reasons, status, and scores
• •Eager build verification runs at upload; miners see verdict immediately via GET /v1/submissions/mine
