v0.2.1

Fixed

• Rate-limited diagnoses now retry. Concurrent runs tripping per-minute provider token limits (429) previously lost the diagnosis entirely. Provider calls retry up to 4 times, honoring the provider's try again in Xs hint, else exponential backoff (capped 90s).
• fix-mode suggestions actually land. Hunk location now tolerates model-mangled diff context: falls back from exact match → indentation-insensitive → removed-lines-only anchoring. Unique match still required at every level.
