docs: Update debug schema documentation to match actual implementation

[promptless]

Updated the debug schema documentation to accurately reflect the implemented debug functionality from the doc-detective-common schema changes. The previous documentation showed an incorrect debug object structure that didn't match the actual schema implementation.

Key corrections made:

Config Schema Updates:

• Updated the debug field to show it accepts boolean or "stepThrough" string values, not an object
• Added proper type definition: one of: boolean, string
• Added detailed description explaining the three modes: false (disabled), true (breakpoints), "stepThrough" (pause at every step)
• Added examples showing all three debug configuration options

Step Schema Updates:

• Added the breakpoint boolean property to the step schema fields table
• Added comprehensive description explaining breakpoint behavior when debug mode is enabled
• Added examples showing steps with breakpoint enabled and disabled
• Positioned the breakpoint field correctly in the common step properties section

Documentation Accuracy:

• Ensures schema documentation matches the actual JSON schema definitions from the PR
• Provides users with accurate examples for configuring debug functionality
• Maintains consistency between the schema reference and actual implementation

This update resolves the discrepancy between the documented debug functionality and the actual schema implementation, ensuring users can properly configure debug mode and step-level breakpoints.
