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. |
