Smarter File Upload, Smoother Agent Experience

1/ File upload logic rebuilt for reliability

Intelligent file type detection, early rejection of oversized files — uploads are faster and parsing is more reliable.

2/ New loading experience while Agent responds

A lighter loading animation while waiting for answers, with curated investment quotes rotating during the wait.

3/ Easier Telegram binding

Simplified flow: Enter your bot token, click the button, and you're paired and authorized.

4/ Polish

• Stabler long conversations: complex tasks run to completion reliably, streaming output uses significantly less memory and bandwidth for smoother conversations
• Error recovery & notifications: sub-Agent calls auto-recover or terminates cleanly on failure; scheduled tasks now notify you explicitly instead of failing silently
• UI refinements: file preview now has close and overflow menus, share dialogs, navigation overlays, and account menus are faster and more polished, announcement popups auto-dismiss after clicking "Learn more"
• Logging sessions extended to 30 days — less frequent re-authentication

5/ Bug Fixes

Fixed Telegram binding cards occasionally flickering or incorrectly showing "unbound" status; file previews now auto-refresh after regeneration; leftover error messages after recovery are cleared automatically.
