docs(plugin-structure): remove extraneous README.md from skill

[sjnims]

Summary

Remove non-conformant README.md from the plugin-structure skill directory.

Problem

Fixes #84

The plugins/plugin-dev/skills/plugin-structure/README.md file doesn't conform to official Claude Code skill structure. Per the skills documentation, skill directories should only contain:

• SKILL.md (required)
• references/ (optional)
• examples/ (optional)
• scripts/ (optional)
• assets/ (optional)

Solution

Delete the extraneous README.md file. All relevant information is already available in SKILL.md.

Alternatives Considered

• Keep and rename to something valid: Rejected - the content is redundant with SKILL.md
• Move to assets/: Rejected - not an asset, and still non-conformant metadata

Changes

• Removed plugins/plugin-dev/skills/plugin-structure/README.md (108 lines)

Testing

• Verified skill directory structure matches official spec
• Linting passes (markdownlint)

Reviewing PR #87: Remove non-conformant README.md from plugin-structure skill

Summary

✅ Looks good - This is a straightforward documentation cleanup that correctly removes a non-conformant file.

---

What's Good

1. Correct Application of Spec: The deletion is appropriate. Per official Claude Code skills documentation, skill directories should only contain:

   • SKILL.md (required)
   • references/ (optional)
   • examples/ (optional)
   • scripts/ (optional)
   • assets/ (optional)

   The README.md file doesn't fit this structure.

2. No Information Loss: After reviewing SKILL.md, all essential information is already present:

   • Comprehensive overview of plugin structure (520 lines)
   • Proper YAML frontmatter with name and description
   • Clear trigger phrases in description
   • References to detailed documentation in references/
   • References to working examples in examples/

3. Clean Directory Structure: Post-deletion structure is compliant:

   plugin-structure/
   ├── SKILL.md
   ├── references/
   │   ├── component-patterns.md
   │   └── manifest-reference.md
   └── examples/
       ├── advanced-plugin.md
       ├── minimal-plugin.md
       └── standard-plugin.md
   

4. Good Commit Message: Follows conventional commits format, includes fix reference, explains rationale.
