feat(ui): add Run interactively action to task context menu

Spawns Windows Terminal in the list working directory running
`claude --permission-mode auto` with the task title and description
prefilled as the initial prompt. Reuses the planning launcher
infrastructure but skips worktree, system prompt, and MCP setup.
