PDFViewer / Margin

Chrome MV3 PDF reader extension for the Margin workflow.

For implementation work, docs/implementation-plan.md is the source of truth. The static UI reference is docs/margin-demo.html.

Current Status

M0, M1, and the first M2 implementation pass are complete. M2 still needs manual Chrome QA for drag highlight, memo restore, and zoom positioning.
