[BUG] Claude Code generates invalid source type in known_marketplaces.json for local plugins

What's Wrong?

When setting up local plugins, Claude Code writes "source": "local" to the marketplace config, but "local" is not a valid discriminator value (valid options are url, github, git, npm, file, directory)

Error: ConfigParseError: Invalid discriminator value. Expected 'url' | 'github' | 'git' | 'npm' | 'file' | 'directory'
Fix: Change "local" to "directory" with a path property
This is a self-inflicted crash which is particularly problematic since users can't easily use Claude Code to fix it when Claude Code won't start.

What Should Happen?

When setting up local plugins, Claude Code should generate valid configuration that allows it to start successfully.
