Permission confirmation, conversations, scene editing updates

Permission confirmation, conversations, scene editing updates

• Added a collapsible role-collaboration view for task handoffs, progress, requests needing attention, and navigation to role conversations.
• Parallel delegations now have their own cards and retain the owning task identity instead of being mixed into the todo list.
• Concurrent questions can be presented together while preserving each request identity so replies reach the correct task.
• Execution notices distinguish connection errors, validation failures, and interruption, and show later activity without hiding the original failure.
• Local file references in conversations offer path copying instead of opening broken browser routes; normal web links remain usable.
• Added an explicit multi-file text-reading tool that retains individual errors and bounds output without silently rewriting single-file reads.
• Escape closes active overlays first and no longer implicitly stops Play, leaving gameplay pause/menu handling to the game.
• Settings invalidation now propagates across same-origin windows, with focus revalidation to refresh cached configuration.
• A failed model-list request preserves the last successful provider-scoped catalog, while an authoritative empty response still clears removed models.
• Feedback delivery status refreshes in the background without hiding existing cards; failed refreshes retain cached reports and polling stops on close.
• Kernel permission changes update only the selected kernel rather than replacing the whole map, reducing unrelated-setting overwrite races.
• Added 3D-library candidate listing, selected-source downloading and validation, and staging before normal editor import.
• Added source-metadata recovery that preserves valid asset identities and rejects escaping paths or invalid existing metadata.
• Play failures now have a dismissible viewport notice with a readable cause and recovery hint instead of only hidden diagnostics.
• Asset-rebuild recovery preserves the last usable snapshot on failure and fences late recovery results after cancellation or session closure.
• Audio verification distinguishes preparation, integration, and real-runtime evidence; passing static checks no longer proves playback.
• Audio-event inspection recognizes direct forwarding wrappers while avoiding shadowed or unrelated same-name playback functions.
• Kernel process adapters support closing input for one-shot calls while retaining piped input for persistent communication.
• Extended application-host interfaces for extension loading, pages, panel contributions, native menus, and context-aware keyboard routing.
• Native context compaction tracks start, completion, failure, and cancellation; manual compaction waits for real completion and deduplicates events.
• History replay avoids repeating processed user inputs and bounds tool-output previews while retaining access to the original session evidence.
