Schematic drafting

• Includes eight organization rules and the supplied visual reference.
• Reviews component placement before wiring; preserves a scoped zero-wire snapshot. Existing wired designs retain their connections.
• Adds connectivity, annotation, page readability, and staged evidence requirements with matching English/Chinese templates.

Validation

27 Python tests and skill structure validation passed. Both language templates initialized successfully; local reference links and the independently extracted archive were checked. A read-only independent agent reviewed three drafting scenarios. No connected EDA drawing or macOS end-to-end validation was performed for this release.

The reference image has separate provenance and licensing notes in THIRD_PARTY_NOTICES.md.
