release: v1.2.0 — fix SkillsMP validation + god-mode + versioning

[vamsivarma27]

Summary

• Fixes the SkillsMP indexing issue — SKILL.md description was over 1024 characters (hard validation failure)
• Bumps version to 1.2.0
• CHANGELOG updated with all changes since 1.1.0

Why the skill wasn't showing on SkillsMP

Two blockers found:

1. SKILL.md description > 1024 chars — SkillsMP validator rejects it silently. Fixed by trimming to a concise single-paragraph description.
2. 0 stars — SkillsMP requires minimum 2 stars to index a repo. Need 2 stars on the repo after merging this.

After merging this PR

1. Star the repo (you = 1 star, need 1 more)
2. Push the v1.2.0 tag to trigger the GitHub Release:

git checkout main && git pull
git tag v1.2.0
git push origin v1.2.0

3. The release workflow auto-creates a GitHub Release with changelog notes
4. SkillsMP expected URL (once 2+ stars): https://skillsmp.com/skills/vamsivarma27-ui-restructure-skill-md

Test plan

• skills validate ./ui-restructure passes
• Merge PR
• Star the repo (need 2 total)
• Push v1.2.0 tag → confirm GitHub Release is created
