Automate Obsidian vault operations and search plain Markdown notes via obsidian-cli.

• Requires obsidian-cli binary; install via Homebrew or manually
• Core commands: search note names or content with snippets, create notes with optional auto-open, move/rename notes with automatic wikilink and Markdown link updates across the vault, and delete notes
• Vaults are standard folders on disk containing .md files, .canvas JSON files, and a .obsidian/ config directory; read the active vault from ~/Library/Application Support/obsidian/obsidian.json rather than hardcoding paths
• Set a default vault once with set-default, then use print-default to retrieve it; supports multiple vaults (iCloud, local, work/personal)
