v0.8.7

This maintenance release improves JSON output for scripting and fixes two live-observed metadata issues.

Added

• Added --json support to source add/delete, notebook delete, and every Studio creation command, including noun-first and verb-first command styles. (#256)
• Added notebook emoji to nlm notebook get --json.
• Added the original question to nlm notebook query --json.

Fixed

• Correctly identify saved mind maps in Studio status instead of labeling them as flashcards.
• Prevent duplicate mind-map entries when NotebookLM returns the same artifact through both status paths.
• Report Drive-picker PDFs as pdf when NotebookLM provides an explicit application/pdf MIME type with its ambiguous source code.

Validation

• Tested all new JSON creation and deletion outputs against a live NotebookLM account.
• Verified all nine Studio creation commands returned real artifact IDs.
• Passed 1,120 automated tests plus Ruff lint and formatting checks.
