📝 Walkthrough

Walkthrough

The PR extends message metadata preservation in chat branching and refines message content filtering. Specifically, generation-related fields (model, generation_time_ms, finish_reason, usage) are now carried over when cloning messages, and message filtering logic validates that content parts contain meaningful data.

Changes

Cohort / File(s)	Summary
Message Branching convex/messages.ts	Added four metadata fields (model, generation_time_ms, finish_reason, usage) to the message cloning operation in branchChat, extending the existing subset of copied fields.
Message Processing lib/chat/chat-processor.ts	Refined message filtering logic to validate content meaningfulness: preserves text parts with non-empty trimmed content, files with URL/fileId, and other part types; filters out messages with no parts or empty parts.

Poem

🐰 A rabbit hops through branching chats,
Preserving metadata—where it's at!
Generation echoes, usage complete,
While filters trim the hollow wheat. ✨
