[Feature Request] chat.z.ai: Add full chat/conversation export capability (Markdown, TXT, DOCX/PDF) for Chat and Agent modes #869

Feature Description & User Need

In the chat.z.ai web interface, users currently have no native option to export or download a complete conversation history from either standard Chat or Agent modes.

As conversations become long, users report severe friction attempting to review earlier context:

• Virtualized message lists and infinite scroll make scrolling back up tedious or cause earlier turns to unload from the DOM.
• Reviewing past solutions, code blocks, or thinking traces requires manual copy-pasting turn by turn.

• User Statement:

  "IF You could to the z.ai website, add in export chat feature where we can choose a conversation in agent or chat, and export the full chat, as txt. or word. etc. Sometimes i want to remember something and have to endlessly scroll up and up and up before i can see it... so the export chat feature would help a lot if its added in."

Proposed Solution

Add an "Export Conversation" action in the conversation header menu / sidebar ellipsis options supporting standard formats:

1. Markdown (.md) / Plaintext (.txt): Clean raw export preserving prompt turns, model answers, code blocks, and collapsible thought blocks.
2. Document / PDF / DOCX: Formatted export suitable for archiving, offline documentation, and sharing.
3. JSON: Raw turn structure with timestamps and token counts for programmatic archiving.

UX Benefits

• Eliminates manual scrolling barriers in deep research and complex coding sessions.
• Allows users to back up their research notes, architectural plans, and agent outputs locally.
