feat: channel info screens

[szuperaz]

1/2 PR for channel details | Figma

This PR implements the 20/25 channel details related Figma screens. The rest will come in a separate PR. The missing screens are implemented in SampleApp (as channel details screens are currently implemented there). All new components/hooks/contexts are marked as experimental by the SDK, the flag will be removed once channel details are fully implemented.

Some follow-up tasks we discovered with Ivan that are not related to channel details, I'll implement it in separate follow-up PRs:

• Move channel actions override to channel preview (and deprecate channel list override?)
• Add capability checks to channel actions
• Add an alert to existing destructive actions
• Add search to members screen
• Fix useChannelMemberOnlineCount
• Finalize role display

Overview of implemented screens:

Some screenshots, mixed from iOS and Android, dark and light theme:

Claude's recap:

The headline of this branch is a brand-new Channel Details screen shipped as a reusable SDK component, with the SampleApp migrated off its old custom overlay implementation.

SampleApp

Removed the entire legacy overlay-based channel info system:

• Overlay infrastructure: AppOverlayContext, AppOverlayProvider, ChannelInfoOverlayContext, UserInfoOverlayContext, OverlayBackdrop, ChannelInfoOverlay, UserInfoOverlay, ContactDetailBottomSheet
• Old member UI: AddMembersBottomSheet, AllMembersBottomSheet, MemberListItem, ChannelDetailProfileSection, and hooks useChannelInfoOverlayActions / useUserInfoOverlayActions
• Old screens: GroupChannelDetailsScreen, OneOnOneChannelDetailScreen, SharedGroupsScreen

Added / updated:

• New thin ChannelDetailsScreen that consumes the SDK component, plus a ChannelDetailsNavigationSection override example
• New SendDirectMessage icon (removed Archive, UserMinus)
• Updated ChannelListScreen, ChannelScreen, NewDirectMessagingScreen, App.tsx, types.ts, and SampleAppComponentOverrides to wire up the new screen

SDK → new

ChannelDetailsScreen component suite (new export from components/index.ts):

• Core: ChannelDetailsScreen, ChannelDetailsProfile, ChannelDetailsActionsSection, ChannelDetailsActionItem, ChannelDetailsMemberSection, ChannelDetailsNavigationSection, ChannelDetailsScreenHeader
• Edit flow: ChannelEditDetails, ChannelEditDetailsModal, ChannelEditName, ChannelEditImageSheet
• Members: ChannelMemberList, ChannelMemberItem, ChannelMemberActionsSheet, ChannelAddMembers (+modal), ChannelAllMembersModal, AddMemberSearchResultItem, and loading skeletons
• Generic Modal / ModalHeader building blocks

New hooks — package/src/hooks/actions/ namespace (useChannelActions, useChannelActionItems, useChannelMemberActionItems, useUserActions, shared types), feature hooks (useChannelDetailsActionItems, useChannelDetailsMembersPreview, useChannelDetailsMemberStatusText, useEditChannelImage, useUserActivityStatus, useChannelAddMembers, useChannelAllMembers, useMemberRoleLabel), and reusable channel hooks now exported publicly: useChannelName, useChannelImage, useChannelMemberCount, useChannelOwnCapabilities, useChannelMuteActive, useIsDirectChat, plus useSyncClientEvents (reactive channel name/image/member-count updates)

New reusable UI / contexts / icons:

• UI components: SearchInput, SelectionCircle, EmptySearchResult
• Contexts: channelDetailsContext and BottomSheetContext
• Icons: chevron-right, x-circle
• ~196 lines of new theme tokens for the new components
• ~50 new translation keys across all 14 locales (member roles, add-members, edit-channel, a11y labels)

SDK → updates to existing

• BottomSheetModal — reworked (~100 lines); fixes the iOS close-callback-fires-too-early bug and now exposes context via the new BottomSheetContext
• ChannelAvatar — extended to show a live preview of pending channel-image changes
• Hook relocations — useChannelActions / useChannelActionItems / useIsDirectChat / useChannelMuteActive moved out of ChannelList/hooks into the shared src/hooks tree (and useChannelActions significantly extended: onFailure/onSuccess handlers, member/image/name updates, separate dismiss API)
• componentsContext — registered the new components as defaults (~31 lines); OwnCapabilitiesContext gained a capability
• ChannelPreview — ChannelDetailsBottomSheet and ChannelSwipableWrapper updated; useChannelPreviewDisplayName / useUserMuteActive tweaked
• camera icon redesign — drove snapshot updates for AttachButton, SendButton, Thread
• notificationTarget — minor update for channel-delete/edit notifications
• Repo housekeeping: CLAUDE.md typecheck note, accessibility skill tweak, new RTL skill

Scale: ~80 commits, +12,961 / −3,635 across 166 files, with a large accompanying test suite (~40 new __tests__ file
