v0.4.37 - Zero-Message Study Program

What changed

• Added codex.mn.studyProgram.v1 to Notebook Workspace.
• The first screen now shows zero-message coverage, concrete gaps, and recommended workflows without requiring a chat prompt first.
• Added visible Study Program controls for coverage, gaps, and workflow recommendations.
• Recommendations reuse existing workflow_start, confirmation, dry-run, and ledger paths instead of adding a write shortcut.
• Doctor and single-document acceptance now require the Study Program controls.

Verification

• python3 -m unittest discover -s tests: 504 tests passed.
• node --check extension/codex.mn.assistant/main.js passed.
• node --check extension/codex.mn.assistant/web/app.js passed.
• Python py_compile for Companion scripts passed.
• Release zip, mnaddon, package build, and install dry-run passed.

Known release gates

• Runtime Web controls and native API evidence require reopening or restarting the MarginNote panel for pluginVersion 0.4.37.
• Native visible highlight evidence, signed package, notarization, cross-machine install evidence, and single-document acceptance remain final release gates.
