feat: register title, resume, and other missing commands with platform menus

Add /title, /resume, /compress, /provider, /usage to Telegram's
set_my_commands so they appear in the / autocomplete menu.

Add /title, /resume, /compress, /provider, /usage, /help as Discord
slash commands so they appear in Discord's native command picker.

These commands were functional via text but not registered with the
platform-native command menus, so users couldn't discover them.
