- getChatMemberCount: channel/supergroup participant count (numeric chat_id).
- getChatMember: resolves a member via GetParticipant, projected to a Bot API
ChatMember (creator/administrator/restricted/member/left/kicked with the
matching rights); a user simply not in an accessible chat returns "left".
- getChat now uses the full channel view and adds permissions (from the default
restrictions), slow_mode_delay, linked_chat_id and pinned_message.
Channel-only methods reject user chat_ids; private chats the bot cannot access
return CHAT_NOT_FOUND.
Adds the getChat method to the HTTP Bot API gateway. Numeric chat_id only (no
@username). Resolution goes through the shared peer resolvers:
- user: ByID; unknown -> CHAT_NOT_FOUND
- channel/supergroup: ResolveChannel, so a public one resolves even when the bot
is not a member (projected as a preview); a private one the bot cannot access
-> CHAT_NOT_FOUND, a banned bot likewise
The Chat projection returns id (bot-api encoded), type ("channel" for a
broadcast, "supergroup" for a megagroup, "private" for a user), title, username,
first/last name, description, is_forum, and the scam/fake/verified flags.
Sync telesrv b96f2dd (feat(bot): complete keyboards callbacks and durable delivery).
Skipped private docs and preserved public README files per sync rules; normalized the appearance seed log label for public naming.
