feat: Add plugin-dev toolkit for comprehensive plugin development

Adds the plugin-dev plugin to public marketplace. A comprehensive toolkit for
developing Claude Code plugins with 7 expert skills, 3 AI-assisted agents, and
extensive documentation covering the complete plugin development lifecycle.

Key features:
- 7 skills: hook-development, mcp-integration, plugin-structure, plugin-settings,
  command-development, agent-development, skill-development
- 3 agents: agent-creator (AI-assisted generation), plugin-validator (structure
  validation), skill-reviewer (quality review)
- 1 command: /plugin-dev:create-plugin (guided 8-phase workflow)
- 10 utility scripts for validation and testing
- 21 reference docs with deep-dive guidance (~11k words)
- 9 working examples demonstrating best practices

Changes for public release:
- Replaced all references to internal repositories with "Claude Code"
- Updated MCP examples: internal.company.com → api.example.com
- Updated token variables: ${INTERNAL_TOKEN} → ${API_TOKEN}
- Reframed agent-creation-system-prompt as "proven in production"
- Preserved all ${CLAUDE_PLUGIN_ROOT} references (186 total)
- Preserved valuable test blocks in core modules

Validation:
- All 3 agents validated successfully with validate-agent.sh
- All JSON files validated with jq
- Zero internal references remaining
- 59 files migrated, 21,971 lines added

Plugin Structure Skill

Comprehensive guidance on Claude Code plugin architecture, directory layout, and best practices.

Overview

This skill provides detailed knowledge about:

Plugin directory structure and organization
plugin.json manifest configuration
Component organization (commands, agents, skills, hooks)
Auto-discovery mechanisms
Portable path references with ${CLAUDE_PLUGIN_ROOT}
File naming conventions

Skill Structure

SKILL.md (1,619 words)

Core skill content covering:

Directory structure overview
Plugin manifest (plugin.json) fields
Component organization patterns
${CLAUDE_PLUGIN_ROOT} usage
File naming conventions
Auto-discovery mechanism
Best practices
Common patterns
Troubleshooting

References

Detailed documentation for deep dives:

manifest-reference.md: Complete plugin.json field reference
- All field descriptions and examples
- Path resolution rules
- Validation guidelines
- Minimal vs. complete manifest examples
component-patterns.md: Advanced organization patterns
- Component lifecycle (discovery, activation)
- Command organization patterns
- Agent organization patterns
- Skill organization patterns
- Hook organization patterns
- Script organization patterns
- Cross-component patterns
- Best practices for scalability

Examples

Three complete plugin examples:

minimal-plugin.md: Simplest possible plugin
- Single command
- Minimal manifest
- When to use this pattern
standard-plugin.md: Well-structured production plugin
- Multiple components (commands, agents, skills, hooks)
- Complete manifest with metadata
- Rich skill structure
- Integration between components
advanced-plugin.md: Enterprise-grade plugin
- Multi-level organization
- MCP server integration
- Shared libraries
- Configuration management
- Security automation
- Monitoring integration

When This Skill Triggers

Claude Code activates this skill when users:

Ask to "create a plugin" or "scaffold a plugin"
Need to "understand plugin structure"
Want to "organize plugin components"
Need to "set up plugin.json"
Ask about "${CLAUDE_PLUGIN_ROOT}" usage
Want to "add commands/agents/skills/hooks"
Need "configure auto-discovery" help
Ask about plugin architecture or best practices

Progressive Disclosure

The skill uses progressive disclosure to manage context:

SKILL.md (~1600 words): Core concepts and workflows
References (~6000 words): Detailed field references and patterns
Examples (~8000 words): Complete working examples

Claude loads references and examples only as needed based on the task.

This skill works well with:

hook-development: For creating plugin hooks
mcp-integration: For integrating MCP servers (when available)
marketplace-publishing: For publishing plugins (when available)

Maintenance

To update this skill:

Keep SKILL.md lean and focused on core concepts
Move detailed information to references/
Add new examples/ for common patterns
Update version in SKILL.md frontmatter
Ensure all documentation uses imperative/infinitive form
