[FEATURE] Estimated time to completion

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

The status line shows elapsed working time but no estimate of how long the task will take. When Claude is working on longer tasks (large refactors, multi-file changes), users can't gauge if it'll finish in 30 seconds or 15 minutes. An ETA lets users decide whether to wait or context-switch.

Proposed Solution

Add an estimated time to completion (ETA) alongside elapsed time — even a rough one like "~3 min remaining" or "~20 min remaining".

Alternative Solutions

• Heuristic based on task complexity (files, tool calls planned)
• Running average from similar past tasks
• Progress based on completed vs remaining steps when a plan exists
