feat(skill-creator): add Step 0 prerequisites check with auto-install

Browse Source 
Adds dependency detection before skill creation starts, preventing
mid-workflow failures (e.g., gitleaks missing at packaging, PyYAML
missing at validation). Documents correct script invocation via
python3 -m syntax and auto-installation commands.

When creating or updating a skill, follow these steps in order. Skip steps only when clearly not applicable.
### Step 0: Prerequisites Check
Before starting any skill work, auto-detect all dependencies and proactively install anything missing. Discovering a missing tool mid-workflow (e.g., gitleaks at packaging time, PyYAML at validation) wastes time and breaks flow.
Run the quick check from [references/prerequisites.md](references/prerequisites.md), auto-install what you can, and present the user a summary checklist. Only proceed when all blocking dependencies are satisfied.
Key blockers: Python 3, PyYAML (validation/packaging), gitleaks (security scan), claude CLI (evals). All scripts must be invoked via `python3 -m scripts.<name>` from the skill-creator root directory — direct `python3 scripts/<name>.py` fails due to relative imports.
### Step 1: Understanding the Skill with Concrete Examples
Skip this step only when the skill's usage patterns are already clearly understood.
