Persistent list of spawned tasks instead of chip-only UI

Problem Statement

When an agent calls spawn_task to flag follow-up work, the result appears as a "chip" / bubble in the UI that can only be launched or dismissed. Two problems:

Dismiss is irreversible. A single accidental click on the X permanently loses the task, including the carefully-crafted prompt and context. There is no undo.
No persistent inventory. If multiple tasks are spawned across different sessions, there is no single place to view them all, see their full prompts, reorder priorities, or recover recently closed ones.
In long projects I often flag follow-up refactors during a session and return to them days later. The chip-only UI is fragile for this workflow — one misclick and the task is gone without trace.

Proposed Solution

Add a dedicated "Tasks" / "Follow-ups" panel in the project view listing all spawned tasks with title, tldr, and timestamp.
Replace hard-delete on X with soft-dismiss — moves to an archive with a visible "recently dismissed" section (e.g. 30 days) so accidents can be undone.
Show full prompt preview on hover or click, not just the tldr tooltip.
Allow editing the prompt or title before launching (useful when context has shifted since it was created).
Add a confirmation or keyboard modifier on the X button to prevent accidental dismissals (or require a two-step delete).
