Add Tampermonkey userscript for SCAU graduate evaluation form auto-fill

[Copilot]

Implements a Tampermonkey userscript to automatically fill evaluation forms in the South China Agricultural University graduate education management system.

Implementation

• scau-grad-auto-fill.user.js (261 lines)
  • Complete Tampermonkey metadata with bilingual support (中文/English)
  • Auto-update URLs pointing to GitHub raw content
  • Page detection via keyword matching on body text and title
  • Form filling logic for radio buttons, select dropdowns, textareas, and text inputs
  • Floating gradient-styled control button (fixed position, top-right)
  • Configurable CONFIG object for scores, delays, and comment templates

Key Technical Decisions

• No auto-submit by default: Requires manual submission after review to prevent accidental form submission
• Placeholder null-safety: Defaults empty placeholder to avoid runtime errors on inputs without placeholder attribute
• Submit button detection: Uses Array.from().find() pattern instead of invalid :contains() CSS pseudo-class
• Event dispatching: Triggers both input and change events for framework compatibility

Example Usage

// User clicks floating button, script executes:
const CONFIG = {
    defaultScore: 5,           // Highest score selection
    fillDelay: 500,            // 500ms between field groups
    autoSubmit: false,         // Manual submission required
    textComments: [/* ... */]  // Random comment selection
};

Security

• CodeQL scan: 0 vulnerabilities
• @grant none - no special permissions required
• Runs only on *.scau.edu.cn domains via @match directives

Documentation

• Installation guide for Chrome/Firefox/Edge/Safari
• Configuration examples and safety warnings
