fix(extension): stop iframe hangs and add debug mode

[arunSunnyKVS]

Problem

On pages with unresponsive cross-origin iframes (e.g. Google Maps embeds), chrome.scripting.executeScript({ allFrames: true }) could block forever. The extension hung at "Detecting chat widget…" / agent-context detection with no timeout or visibility into what failed.

Separately, Chat360/Draft.js widgets nest message text deeper than the snapshot walker’s depth-15 limit, so bot replies were never extracted even when sends succeeded.

Solution

• Wrap allFrames scripting paths in Promise.race timeouts with main-frame-only fallbacks (collectFrames, AX snapshots, shadow patch, response scan, agent-context summarize).
• Raise frame_snapshot.js collect depth from 15 → 25 so deeply nested message bodies are captured.
• Add an extension debug mode (debugLog.js + popup toggle / export / clear) that logs locate, LLM UI actions, send, and extract steps to the service worker + storage.
• Improve frame_actuate.js failure details when submit is not accepted.

Changes

• runners/extension/debugLog.js (new)
• runners/extension/{agentContext,chatLocator,domActions,domTarget,frameDiscovery,frame_actuate,frame_snapshot,llm,llmUiActions,orchestrator,popup,responseExtractor,service_worker}.*

Issue

N/A

How to test

1. Load unpacked runners/extension in Chrome.
2. Open Advanced → enable Debug mode.
3. Run against a page that previously hung (e.g. hospital site with Maps iframe) — locate should progress past allFrames within ~15–45s via fallback instead of hanging forever.
4. Run against a Chat360 widget (e.g. hyundai.com/in) — after send, response extraction should capture bot text (depth fix).
5. Export logs from Advanced and confirm locate / LLM / send / extract events appear.

Screenshots

N/A — debug toggle lives under Advanced settings in the side panel.
