feat: add admin/owner permission system

Browse Source 
Hostmask-based admin controls with automatic IRCOP detection via WHO.
Permission enforcement in the central dispatch path denies restricted
commands to non-admins. Includes !whoami and !admins commands, marks
load/reload/unload as admin-only.

Also lands previously-implemented SASL PLAIN auth, token-bucket rate
limiting, and CTCP VERSION/TIME/PING responses that were staged but
uncommitted.
