Create scripts/stats.mjs — live identity stats

[VisionaireLabs]

Task

Build scripts/stats.mjs that outputs a JSON snapshot of Visionaire's current state.

Requirements

Stats to compute:

• days_alive: days since born (Nov 24, 2024)
• contemplations: count of files in memory/contemplations/
• knowledge_entries: count of entries in memory/knowledge.json (if exists)
• feedback_entries: count of entries in memory/feedback.json (if exists)
• daily_notes: count of files in memory/ matching YYYY-MM-DD.md pattern
• generated_at: ISO timestamp

Output

{
  "days_alive": 117,
  "contemplations": 42,
  "knowledge_entries": 38,
  "feedback_entries": 7,
  "daily_notes": 22,
  "generated_at": "2026-03-21T00:00:00.000Z"
}

Acceptance Criteria

• Script runs with node scripts/stats.mjs
• Outputs valid JSON to stdout
• Handles missing optional files gracefully (returns 0, not error)
• No external dependencies (Node stdlib only)
