Subject: [PATCH] fix(publisher): support --file flag in publish command

Added proper flag parsing using the flag package so that
'mcp-publisher publish --file path/to/server.json' works correctly.

Also improved error messages to show the actual file path when
a custom file is specified but not found.

Fixes #767
