Create scripts/health-check.mjs — repo integrity validator

[VisionaireLabs]

Task

Build scripts/health-check.mjs that validates the Visionaire repo is in a healthy, consistent state. Exit code 0 = healthy, 1 = problems found.

Checks to implement

1. Required files exist: SOUL.md, AGENTS.md, USER.md, MEMORY.md, HEARTBEAT.md, TOOLS.md, SOUL.md
2. Scripts are valid JS: parse-check all .mjs files in scripts/
3. JSON files are valid: parse any .json in memory/
4. memory/ structure: check memory/ directory exists
5. Cron dir: check cron/ directory exists

Output format

✅ Required files: 7/7 present
✅ Scripts valid: 3/3 pass
⚠️  JSON files: 1/2 valid (memory/feedback.json: SyntaxError line 42)
✅ Directories: memory/, cron/ present

2 warnings, 0 errors

Acceptance Criteria

• node scripts/health-check.mjs exits 0 on clean repo
• Exits 1 if any required file is missing
• Colorized output (use ANSI codes directly, no deps)
• Summary line at end with counts
