Channel Discovery:
- Remove channel/supergroup filter from getAccountChats — all chat types
(private, groups, Saved Messages, etc.) are now discoverable as sources
- Detect and label the self-chat as "Saved Messages" via getMe
- Update channel picker dialog to accept any chat type string
Bot Rich Messages:
- Enhance package send preview with creator, file count, tags, and source
channel info in MarkdownV2 caption
- Include tags in new_package subscription notifications
- Expand getPendingSendRequest to fetch richer package data
Performance:
- Reviewed pipeline for many-channel load — getChats pagination fix and
per-channel getChat pre-load from prior commit address the main concerns
- Channels with no new messages skip in 2-3 API calls
