plan: ticket CLI-driven reader open (T-231)

Dogfooding showed Epic C gave the CLI the observe half of D-6 parity
but not the drive half: no verb opens a doc in a UI reader because
nothing bridges the IPC layer to the kernel MessageBus. Files T-231
to add a ui.open/view.open verb under T-208.

Today the only interactive setter is the team meta-sidebar per-agent control (claude_meta_sidebar.dart:342); the primary pane has none. There is a command claude.agent.set-permission-mode <sessionId> <mode> (extension.dart:148) but it needs an explicit id + explicit mode, and there is no ''cycle'' verb. setPermissionMode() over the stream-json control channel already works (stream_json_session.dart:671, D-78). Scope: (1) add a mode-cycle action that targets the focused/primary session and advances the safe trio default -> acceptEdits -> plan -> default (bypassPermissions only via a confirmed/explicit path, per the T-181 footgun guard); (2) bind it to Shift+Tab INTERCEPTED at the focused Claude composer -- note shift+tab is globally focus.previous (default.yaml:31), so this needs consumer-level interception like the Vim editor (D-82), falling back to focus traversal elsewhere; (3) make the status-line mode label a clickable badge that cycles on click (the ''cockpit badge'' the stream_json_session comment already promises at line 668-669). Relates to T-181, D-77/D-78, D-82.
 
 Refinement (2026-06-03): Shift+Tab is REJECTED as the trigger — Tab/Shift+Tab are real a11y focus-traversal intents (focus.next/focus.previous) since T-204, so hijacking Shift+Tab would break keyboard navigation. Instead: (a) Ctrl/Cmd+M cycles, intercepted at the focused Claude composer (so it targets that pane''s session, no global ''find focused session'' needed); (b) the status-line mode label becomes a FOCUSABLE button — cycles on click and on Enter/Space when focused (a11y-native, Tab reaches it); (c) a ''Claude: Cycle permission mode'' palette command.

The DRIVE half is missing: there is no CLI/IPC verb that opens a doc in a UI reader. Opening a ticket/decision/markdown doc happens only inside the Flutter app, by publishing to the kernel MessageBus (e.g. messages.publish(''builtin.tickets'',''selection'',{''id'':id}); see tickets/src/extension.dart:29 which subscribes publisher ''builtin.tickets'' channel ''selection'', and ticket_detail_view.dart). lib/src/daemon/ has NO verb that reaches the MessageBus, so an agent cannot say ''look at this with me''. Proposed: add a bridge verb (e.g. ui.open / view.open <publisher> <id-or-path>) that publishes a ''selection'' message to the bus, so ''clide ui open tickets T-48'' opens T-48 in the ticket reader (and decisions/markdown analogously). Wiring: thread the kernel MessageBus into the dispatcher the same way panels/readerNav were threaded for T-219/T-221 (daemonClientFactory param or post-boot capture in main.dart).
