v0.5.2

Features:

• --retry-failed on eb run and eb eval. Re-runs only the rows whose underlying Claude call errored in an existing snapshot (run.error !== null); successful rows are kept verbatim. Resolves the "I lost a few runs to a judge timeout yesterday — how do I top up without redoing all 30?" case. Mutually exclusive with --force. Errors clearly if the snapshot doesn't exist or has no failures (the latter short-circuits with exit 0).

Internals:

• pruneFailedRuns(snap) exported from src/snapshot.ts — drops failed runs and their judgments, sets complete: false, returns counts. The CLI feeds the result to the existing resume path, which already knows how to re-execute the now-missing rows.
