feat: strip all mentions from relayed messages by default (v3.4.3)

Browse source 
- Default mention_policy now disables all mention types including user
  mentions (previously allow_user_mentions defaulted to True)
- Blocked mentions are now removed entirely instead of replaced with
  ZWSP placeholders — '@mention HI!' becomes 'HI!' on the other side
- Trailing whitespace from removed mentions is cleaned up
- Updated both apply_mention_policy() and sanitise_mentions()
