Add Discord role inheritance via parent traversal and discordImplies

Browse source 
- Add discordImplies field to Role interface for Discord-specific role hierarchy
- Add expandDiscordRoles() function to traverse both GitHub parent chain
  and discordImplies relationships when syncing Discord roles
- SDK_MAINTAINERS now implies MAINTAINERS for Discord

This ensures that users with SDK roles (GO_SDK, PYTHON_SDK, etc.) automatically
get the 'maintainers (synced)' Discord role through:
  GO_SDK -> SDK_MAINTAINERS (via GitHub parent) -> MAINTAINERS (via discordImplies)
