Patch Changes

• #1542 f80b2ea Thanks @wbxl2000! - web: Fix the "Turn finished" desktop notification and completion sound firing twice per turn.

• #1535 04041eb Thanks @wbxl2000! - web: Hide the internal image-compression note so it no longer renders as user message text.

• #1536 db61c9e Thanks @RealKai42! - Stop unsupported image formats (AVIF, BMP, TIFF, ICO, …) from breaking sessions at every entry point — including remote image URLs and images mislabeled by a tool — and recover an already-stuck session by dropping the offending image and retrying, so one such image can no longer make every later request fail.

• #1530 9f66ec4 Thanks @sailist! - Retry provider 429, overload, and other transient errors more reliably, honoring the server Retry-After delay, and surface retries in -p --output-format stream-json.
