## Summary
- fix Step 5 field detection to prefer visible `input[name="age"]`
- stop treating hidden `input[name="birthday"]` as a birthday-mode signal
- preserve birthday-mode handling for visible birthday controls
## Problem
On some pages, a visible age input and a hidden birthday input coexist.
The previous logic treated the hidden `input[name="birthday"]` as evidence of birthday mode, which caused Step 5 to
fill birthday instead of age.
## Verification
- reproduced on a page where `input[name="age"]` is visible
- confirmed `input[name="birthday"]` exists but is hidden
- verified Step 5 now enters the age branch and fills the age input correctly
- Implemented a new content script for DuckDuckGo Email autofill functionality.
- Enhanced email polling scripts (mail-163.js, qq-mail.js, signup-page.js, vps-panel.js) to handle user flow interruptions.
- Updated utility functions to manage flow stopping and error handling.
- Introduced a stop button in the side panel for user control over ongoing processes.
- Improved UI elements and styles for better user experience, including new button states and messages.
- Adjusted the side panel to fetch DuckDuckGo email automatically and display it in the input field.
- Remove dead chatgpt.js (unused — all auth flows go through signup-page.js)
- Remove chatgpt.com from manifest content_scripts
- Fix resetState() to preserve vpsUrl and mailProvider on manual reset
- Add 30s timeout to all tabs.onUpdated listeners (prevent hanging)
- Fix misleading "All runs finished" log when loop breaks early
