Lower the username floor to 3 characters on the admin-only write path
(account/channel set-username), separate from the 5-character self-service
minimum, since a deliberately short operator handle isn't the squatting the
higher floor guards against. Channel admin username assignment previously
had no length/format validation at all; this adds it.
Also adds three reference docs: the client's deep-link (tg://, owpg://)
surface, an OpenAPI 3.1 spec for both admin HTTP APIs (built from source,
not the stale docs/admin-panel-api.en.md), and a starter reserved-username
blocklist.
Feature-by-feature comparison across transport/auth, messaging, groups,
media, bots, calls, stories, secret chats, sync, themes, moderation, and
the payments/Stars economy - marking each Full / Partial / Stub / None,
with the deliberate omissions and OwpenGram-only additions called out
separately.
Follow up PR #22 by projecting its composite rating through userFull while keeping profile reads cache-backed and strictly read-only.
