Subject: [PATCH] fix(opencode): handle shell-escaped parentheses in drag-drop
 file paths

Terminals like Ghostty shell-escape special characters when drag-dropping
files. The paste handler only unescaped backslash-space but not other
metacharacters like parentheses, causing silent attachment failure for
filenames like 'image (1).png'.

Use /\\([^a-zA-Z0-9])/g to unescape all shell metacharacters while
preserving Windows path separators (backslash + alphanumeric).

Fixes #17075
