- 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.
ListChannelReplies used getChannelForMemberOrLinkedGuest, so messages.getReplies
was member-only. ListChannelHistory (flat history) uses getChannelForViewer and
already allows a public channel's non-members to preview it. The mismatch meant
that on a public forum you could preview the flat history but not the topics -
and after leaving, tdesktop's topic view got CHANNEL_PRIVATE and sat on
"Loading..." forever instead of rendering a preview.
Switch the primary channel lookup in ListChannelReplies (both stores) to the
viewer-scope path. Private channels still return CHANNEL_PRIVATE to non-members;
the broadcast comment-thread lookup is unchanged.
messages.getForumTopics returned every chat via tgChannels -> tgChannelChatMin,
so the forum's own channel came back as a min object with left unset. A client
with no other object for that peer (a fresh account browsing a public forum by
username) then rendered the forum as already joined: topic list visible, no
Join button, but no messages.
Render the primary channel with tgChannelChatForView so a non-member preview
carries left=true; keep the other referenced channels as min.

After channels.leaveChannel, a client that polls channels.getFullChannel kept
receiving a projection that still showed it as an active member (left=false)
until the per-(viewer,channel) RPC projection cache and the store-level member
cache lapsed on their own or the async read-model NOTIFY landed. The client
therefore kept an open compose box while every send was already rejected with
CHANNEL_PRIVATE - most visible on public forum supergroups, where getFullChannel
keeps succeeding via the preview path instead of tearing the chat down.
Every other membership-mutating path already busts these caches synchronously;
join/leave/invite/request-approval did not. Add:
- store: invalidateChannelMembershipCaches (row + member + dialog caches),
called post-commit from JoinChannel, LeaveChannel, ImportInvite,
InviteToChannel.
- rpc: invalidateChannelMembershipProjection (channelFullProjectionCache pair),
called from the join/leave/invite/hide-requests handlers for every user whose
membership changed.

resolveChannelReply applied discussion-thread logic (reply_to_top_id =
the replied-to message's own id) to forum replies. Replying to a General
message produced reply_to_top_id = <that id>, a topic no client can
resolve: the reply vanished from every topic view and reply-jump on
strict clients said "message doesn't exist".
Forum replies now inherit the target's topic via domain.ForumReplyTopicID
(target's topic, or its own id if it's a topic-create, else General), and
General (topic 1) is accepted as a valid virtual topic everywhere, so
sends carrying top_msg_id: 1 are no longer rejected. Non-forum discussion
threads are unchanged.

ListForumTopics / GetForumTopicsByID / GeneralForumTopic gated on
membership while channel history uses the public-preview path, so a
public forum's topics (General included) were invisible until you joined.
Switch them to getChannelForViewer / channelForViewerLocked; private
forums and write paths keep the membership gate.

A channel post containing an @token that is not a syntactically valid
username (too short, leading digit, etc.) made messages.sendMessage return
500 INTERNAL_SERVER_ERROR: mentionedUserIDsFromMessage turned every
ResolveUsername error into internalErr().
Skip tokens that fail with ErrUsernameInvalid / ErrUsernameNotOccupied
instead, matching real Telegram (the message sends, the client renders the
mention and only fails to open it on tap). Only unexpected storage errors
still abort. Same fix applied to the bot send path.
