Koichi ITO	37563e59bd	Fix Content::Image#to_h to return mimeType (camelCase) per MCP spec ... This is a fix for a similar bug that remained, as in #235. `Content::Image#to_h` returned `mime_type` (snake_case), but the MCP spec requires `mimeType` (camelCase) for the MIME type field in image content.	2026-02-27 12:51:38 +09:00
