Subject: [PATCH] Add --marketplace-url global CLI flag

Add a global --marketplace-url option that overrides the target
marketplace endpoint for all commands (publish, unpublish, show,
search, etc.). This enables publishing extensions to private or
alternative marketplace instances without relying solely on the
VSCE_MARKETPLACE_URL environment variable.

Precedence: --marketplace-url flag > VSCE_MARKETPLACE_URL env var > default

Example:
  vsce publish --marketplace-url https://private.example.com
