v0.5.11

Added

• Enterprise / Google Workspace support (PR #114) — Configurable base URL via NOTEBOOKLM_BASE_URL environment variable. Set to https://notebooklm.cloud.google.com (or your organization's URL) to use NotebookLM with managed Workspace accounts. All API calls, authentication, file uploads, and URL detection are updated to use the configured base URL. Default remains https://notebooklm.google.com for personal accounts (fully backward compatible). Thanks to @Robiton for this contribution!

Documentation

• Added "Enterprise / Google Workspace" section to docs/AUTHENTICATION.md
• Added NOTEBOOKLM_BASE_URL to environment variables table in docs/MCP_GUIDE.md
