Automatically remove active-state labels when an email is archived or deleted

Inbox Zero should support automatically clearing active-state labels when an email is no longer active. Examples:

• To Reply

• Action

• Awaiting Reply

• Urgent

Why this matters

These labels describe the current state of an email in the inbox. If an email gets archived or deleted, it is no longer active, so those labels should not remain attached.

Current problem

Right now, an email can be:

• archived or deleted

• but still keep labels like To Reply, Action, Awaiting Reply, or Urgent

That creates confusion because the labels stop reflecting reality.

Desired behavior

When an email is archived or deleted, Inbox Zero should be able to:

• automatically remove selected active-state labels, or

• let users configure labels that only apply to active inbox items
  

Why this is important

Without this, labels become stale and misleading. A label like Awaiting Reply or Action should only exist while that email is still actively in play.

Request

Add support for automatic label cleanup on archive/delete, especially for labels that represent active workflow state.
