Koduri Mahesh Bhushan Chowdary b3f4f50771 fix(agent): classify "media exceeds size limit" as image_too_large
MiniMax's Anthropic-compatible endpoint rejects an oversized native image
part with "media exceeds size limit: max 10485760 bytes (2013)" — no
occurrence of the word "image", so none of _IMAGE_TOO_LARGE_PATTERNS
matched. The 400 fell through to _REQUEST_VALIDATION_PATTERNS (the body
is type: invalid_request_error) and classified as format_error /
non-retryable.

That skipped the image-shrink recovery in conversation_loop, which is
gated on FailoverReason.image_too_large. Because the oversized part is
already baked into history as a tool_result image block, and the context
compressor rewrites text but not image data, every later turn re-sent the
same bytes and failed identically — the session stayed dead until the
user forked it.

Match on the "media" fragment, mirroring the existing "image exceeds"
entry so reworded vendor variants are caught too. A non-image media
rejection routed here is safe: the shrink pass finds no image parts,
returns False, and the caller surfaces the original error unchanged.

Fixes #76039
