v0.8.2

This release improves background-task visibility and session lifecycle handling, and adds permission management for embedded Claude Code.

• Show running subagents in session panes, the dashboard, and session summaries; keep worktrees marked as working while background tasks run.
• Report one continuous busy span while AI sessions wait for background tasks.
• Correctly finish stopped or orphan-summarized Claude tasks and recover sessions left finishing by abandoned permission prompts.
• Add /permissions for embedded Claude Code.
• Fix file-picker folder listings for paths ending in a slash.
