Fix Claude Code setup skill: move to .claude/commands/ and update README

[Copilot]

claude /setup fails with "unknown skill" because the skill file lives in .claude/setup/SKILL.md instead of Claude Code's expected .claude/commands/ directory. The file also still references the old project name "VibeLab".

Changes

• Move skill file from .claude/setup/SKILL.md → .claude/commands/setup.md (standard Claude Code custom commands path)
• Fix stale references: "VibeLab" → "InnoClaw", vibelab.db → innoclaw.db; drop redundant name frontmatter field (derived from filename)
• Update .gitignore allowlist from .claude/setup/ to .claude/commands/
• Rewrite README Quick Start with explicit 3-step instructions and a warning about the correct invocation:

# Step 1: Clone
git clone https://github.com/zjowowen/InnoClaw.git && cd InnoClaw

# Step 2: Enter Claude Code
claude

# Step 3: Inside Claude Code, run:
/project:setup

⚠️ claude /setup directly in terminal → "unknown skill" error. Must enter Claude Code first, then invoke /project:setup.
