docs(skill-development): update validation checklist and clarify reference file purposes

[sjnims]

Summary

• Adds name format rules (lowercase letters, numbers, hyphens, max 64 chars) to validation checklist
• Adds description length limit (1024 chars) to validation checklist
• Clarifies reference file descriptions to explain when to use each

Problem

Fixes #41

The skill-development SKILL.md validation checklist was missing format requirements documented in official Claude Code docs. Additionally, the two reference files were listed without explaining when to use each.

Solution

Updated the validation checklist Structure section to include:

• Name format validation (lowercase letters, numbers, hyphens, max 64 chars)
• Description length check (under 1024 characters)

Updated reference file descriptions to clarify purpose:

• skill-creation-workflow.md - Plugin-specific workflow (recommended for plugin skills)
• skill-creator-original.md - Generic methodology (includes standalone skill scripts)

Changes

• plugins/plugin-dev/skills/skill-development/SKILL.md: Added 2 checklist items, updated 2 reference descriptions

Testing

• Markdownlint passes
• Changes match acceptance criteria in issue

What's Good

Strong improvements to validation checklist:

• Adds missing name format validation (plugins/plugin-dev/skills/skill-development/SKILL.md:201-202) - correctly specifies lowercase letters, numbers, hyphens, and 64-char max

• Both additions are properly placed in the Structure section where they belong

Clearer reference file descriptions:

• The updated descriptions at lines 302-303 now explain the key distinction:
