Windows cmd.exe interprets % as environment variable prefix, causing
Git format placeholders (%H, %an, %ad, etc.) to be treated as undefined
variables instead of being passed to Git. This resulted in empty author
names and missing commit data in the Local Git changelog view.

Changes:
• Add Windows-specific % escaping (double %% for cmd.exe)
• Apply platform-specific date format handling
• Fix body parsing with explode limit to handle || in messages
• Remove escapeshellarg from format string to allow Git expansion
