Add AI-optimized documentation for programmatic usage

[Copilot]

Description

AI agents and chat interfaces lacked structured documentation for programmatic Doc Detective usage. Added dedicated guides with complete JSON examples, parameter tables, and error solutions to reduce implementation friction from hours to minutes.

Type of contribution

• Quick change (typo, broken link, small wording change)
• Standard change (new content, examples, or improvements)
• Substantial change (new feature docs, major restructuring, tutorials)

Changes made

New pages:

• quick-start-for-ai.mdx - Structured guide: minimal examples, test specs, action patterns, output format, CLI args, error handling, CI/CD integration
• api-reference.mdx - Complete action reference: 15 actions with parameter tables, return values, usage patterns
• troubleshooting.mdx - 15+ error scenarios with symptoms/causes/solutions, debugging strategies, Docker issues

Enhanced existing:

• README.md - Added AI usage section with minimal example
• intro.mdx - Emphasized JSON format and structured output
• concepts.md - Added JSON structures for all concepts, action categories, result types
• httpRequest.mdx, runShell.mdx - Added quick reference summaries

Example impact:

// Before: Piecing together from multiple pages
// After: Complete working example in one place
{
  "tests": [{
    "steps": [
      {"action": "goTo", "url": "https://example.com"},
      {"action": "find", "selector": "#submit", "click": true},
      {"action": "screenshot", "path": "result.png"}
    ]
  }]
}
