Improve autoresearch live observability

[MattPua]

Problem

Autoresearch runs did not clearly expose live progress, current findings, or pause-aware timing.

Changes

• Add a responsive, collapsible live timeline with newest-first activity, timestamps, statuses, command tooltips, and loading states
• Add current findings, sorted observed-time categories, and expandable iteration summaries
• Track pause intervals so runtime and observed time exclude paused or interrupted periods
• Improve accessibility, truncation, container queries, and Quill component usage

How did you test this?

• Core autoresearch tests: 161 passed
