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.

New supergroups are created with "chat history for new members" hidden (the
client sets this right after creation, matching official Telegram). The
official server then forces it back to visible when the group is made public;
owpengram's UpdateUsername left the flag alone, leaving public groups in a
state where non-members (and post-join members) see no history at all.
UpdateUsername now clears pre_history_hidden whenever a non-empty username is
assigned, in the same transaction, with a matching admin-log event. Removing
the username leaves the flag untouched, so the creator can hide history again
once the group is private.

cachedParticipants returned a participant page with Hash=0 whenever the
channel_base / channel_participants rows in read_model_versions were never
seeded for a channel (e.g. groups created via messages.createChat). With
Hash=0 the RPC layer can never answer channels.channelParticipantsNotModified,
so a client that polls the member list re-fetches it in a tight loop forever.
Fall back to a deterministic content hash derived from the page itself
(channel id, page key, count, and each member's id/role/status/rank) so an
unchanged member list yields an identical non-zero Hash and the client
converges. The read-model-backed path is unchanged.

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.

- Edit Bot now shows the current value of every field (Name/About/
Description/Botpic/Commands) like BotFather, with real botpic status
via a new PeerHasAvatar port method.
- After editing a field the dialog lands back on a fresh Edit Bot menu
(working "Back to bot" / "Bots list" buttons) instead of ending, so a
follow-up button press no longer reports the button as expired.
- Service-bot messages now render @username as a tappable mention entity.
Button-driven bot management: paginated picker, per-bot API token /
revoke, Edit Bot (name/description/about/commands/botpic), Bot Settings
toggles (inline/groups/privacy), and delete. Navigation edits the menu
message in place via a new editServiceBotMessage helper.
Edit Botpic accepts a photo the user sends to @BotFather and sets it as
the bot's profile photo (new files.SetAvatarFromExistingPhoto, wired
through bots.SetBotUserpic / WithBotAvatarStore); photos.uploadProfilePhoto
does not accept a bot target so this is the only route.
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.
