feat: enhance skill-development description with stronger triggers

[sjnims]

Summary

Enhance the skill-development skill description with stronger trigger phrases to improve Claude's ability to recognize when this skill should be activated.

Problem

Fixes #3

The skill-development skill had only 5 trigger phrases, making it the weakest description among the 7 plugin-dev skills. As a meta-skill teaching description best practices, it should exemplify those practices.

Solution

Added 8 new trigger phrases following the gold-standard pattern from hook-development:

New trigger phrases:

• "SKILL.md format" - file reference
• "skill frontmatter" - technical term
• "skill triggers" - technical term
• "trigger phrases for skills" - concept
• "progressive disclosure" - already existed, now quoted
• "skill references folder" - folder reference
• "skill examples folder" - folder reference
• "validate skill" - action phrase

Also expanded keywords:

• Added: file organization, writing style

Alternatives Considered

• Minimal enhancement: Only add 3-4 phrases. Rejected because the issue requested at least 10 total.
• Maximum enhancement: Add 20+ phrases. Rejected to avoid cluttering the description and stay well under the 1024 char limit.

Changes

• plugins/plugin-dev/skills/skill-development/SKILL.md: Updated description frontmatter field

Acceptance Criteria

• Description includes at least 10 specific trigger phrases (now has 13)
• Covers file/folder references (SKILL.md, references/, examples/)
• Includes technical terms (frontmatter, triggers, progressive disclosure)
• Maintains third-person format ("This skill should be used when...")
• Stays under 1024 character limit (484 chars)

Testing

• Markdownlint passes
• Character count verified (484 < 1024)
