feat: full Copilot SDK feature parity — custom agents, hooks, image input, skills, steering, session persistence
Backend (sidecar): - Extended ProtocolModels with DTOs for custom agents, hooks, skills, infinite sessions, session lifecycle, and 9 new event types - Added CopilotManagedSessionIds for stable SDK session ID mapping - Added CopilotSessionManager/ICopilotSessionManager for session lifecycle - Added CopilotSessionHooks for hook registration - Added CopilotMessageOptionsMetadata for mid-turn steering - Extended CopilotAgentBundle to wire custom agents, hooks, skills, infinite sessions, and stable session IDs - Extended CopilotTurnExecutionState to project 13 new SDK event types - Widened ITurnWorkflowRunner callback to accept SidecarEventDto - Added list/delete/disconnect session commands to SidecarProtocolHost - Added AryxCopilotAgentMessageOptionsTests (14 new tests, 142 total) Frontend (renderer + main + shared): - Added ChatMessageAttachment type and helpers (attachment.ts) - Extended sidecar contracts with MessageMode, 3 new command types, 9 new event types, and agent/session config DTOs - Extended SessionEventRecord with 6 new event kinds and ~20 fields - Added PatternAgentCopilotConfig to pattern domain - Added attachments support to ChatMessageRecord - Updated sidecar client with session lifecycle methods and turn-scoped event routing via onTurnScopedEvent callback - Updated main process: handleTurnScopedEvent(), deleteSession(), steering bypass for mid-turn messages, attachment passthrough - Added deleteSession IPC handler and preload binding - Added TurnEventLog state tracker with format/apply/prune helpers - ChatPane: always-enabled composer, steering indicator, attachment picker with preview, image thumbnails in message history, context-usage bar, amber steer mode for send button - ActivityPanel: turn events section with sub-agent, hook, skill, and compaction event rendering - Sidebar: delete session action in context menu - App.tsx: wired sessionUsage, turnEventLogs, and deleteSession Documentation: - AGENTS.md: added glob safety rule for node_modules - README.md: added steering, image input, and richer observability - ARCHITECTURE.md: added turn-scoped events, steering, and attachments - Website: added steering and image input feature cards, updated live visibility and session cards Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
