Greptile Summary

Added two new Tomorrow-themed editor themes (Tomorrow Night and Tomorrow Night Bright) and implemented API filtering to show only CodeMirror-compatible plugins in the marketplace.

Key Changes:

• Added Tomorrow Night and Tomorrow Night Bright themes following the existing CodeMirror theme pattern
• Modified plugin marketplace to append supported_editor=cm query parameter to all API requests
• Ensures users only see plugins compatible with the CodeMirror editor currently in use

Confidence Score: 5/5

• This PR is safe to merge with no issues found
• The changes follow existing patterns perfectly, add useful functionality, and have no logic or syntax errors. The theme implementations are consistent with other themes in the codebase, and the API filtering is implemented consistently across both plugin interfaces.
• No files require special attention
