Subject: [PATCH] feat: hint Claude to read image files with Read tool

When a WeChat image is received, the extracted content now includes
a prompt telling Claude to use its Read tool to view the image file.
Previously, only the file path was passed as plain text, so Claude
had no cue to actually look at the image content.
