Scriptorium Nostr - Obsidian Plugin Startup Script

USAGE:
    $0 [OPTIONS] [vault-path]

OPTIONS:
    -h, --help          Show this help message
    --generate-key      Generate a new Nostr private key

ARGUMENTS:
    vault-path          Path to your Obsidian vault folder
                        Required on first run, optional afterwards

EXAMPLES:
    $0 ~/Documents/MyVault          # First run
    $0                              # Use saved vault path
    $0 --generate-key               # Generate new Nostr key
    $0 --help                       # Show this help

WHAT THIS SCRIPT DOES:
    1. Installs npm dependencies (if needed)
    2. Builds the Scriptorium plugin
    3. Installs plugin to your vault
    4. Installs obsidian-asciidoc plugin (for .adoc files)
    5. Starts Obsidian with console logging

NOTES:
    • Vault path is saved after first run
    • obsidian-asciidoc is installed automatically
    • Plugin logs appear in this terminal
    • Press Ctrl+C to stop Obsidian
