docs(agent-development): enhance content completeness and documentation

[sjnims]

Summary

Enhances the agent-development skill with improved documentation completeness:

• Model selection guidance explaining when to choose haiku/sonnet/opus
• Enriched Additional Resources section with detailed file descriptions
• Full copy-pasteable script path in Implementation Workflow
• Note about tools vs allowed-tools field naming difference

Problem

Fixes #19

Solution

Added four targeted enhancements to improve discoverability, actionability, and clarity:

1. Model Selection Guidance - Added "When to choose" section with clear use cases for each model option
2. Reference File Descriptions - Expanded 1-line descriptions to explain what each reference file provides
3. Full Script Path - Changed relative path to full runnable path with example filename
4. Component Difference Note - Added blockquote explaining the tools vs allowed-tools naming difference

Alternatives Considered

• Considered adding model guidance to a separate reference file, but inline guidance is more discoverable
• Considered detailed multi-paragraph descriptions for reference files, but kept concise to maintain lean SKILL.md

Changes

• plugins/plugin-dev/skills/agent-development/SKILL.md: All four documentation enhancements

Testing

• Markdown linting passes
• Word count remains in ideal range (1,752 words < 2,000 target)
• All changes match issue acceptance criteria
