Add NoteDiscovery v0.16.3 - Private Self-Hosted Knowledge Base

Description

NoteDiscovery is a lightweight, privacy-first note-taking app and knowledge base. Notes are stored as plain markdown files — no vendor lock-in, no data sent to external services. An open-source alternative to Obsidian and Notion.

Key Features:

• Plain markdown file storage with no vendor lock-in
• Graph view for visualizing connected notes
• Instant full-text search across all notes
• LaTeX/MathJax mathematical equation support
• Mermaid diagram creation
• HTML export functionality
• Built-in password protection
• Dark and light mode

Technical Implementation:

• Single container architecture: NoteDiscovery (Python)
• $PCS_DEFAULT_PASSWORD for authentication (no hardcoded credentials)
• Authentication enabled by default
• Caddy reverse proxy labels for clean HTTPS URLs
• Port 80 exposed for clean NSL Router URLs
• Built-in healthcheck on /health endpoint
• Multi-language support (English, Korean, Chinese, Spanish, French)

Architecture:

User → Caddy (HTTPS) → NoteDiscovery (port 80) → Markdown files (data volume)
