[codex] Extract Pro

[joesobo]

Summary

• Adds the public Plugin API/Core foundation for Extract Pro: Access providers, plugin data storage, and Graph View runtime/projection/context-menu/UI/force contribution contracts.
• Hosts those Graph View contributions in the extension runtime, including runtime nodes/edges, projections, additive D3 force adapters, context-menu selectors, and named UI slots.
• Adds the public @codegraphy/pro package shell, the @codegraphy/web app target, and codegraphy plugins link <package-root> for local private plugin development.
• Updates plugin docs, release/quality contracts, and changesets for the new package/API surface.

Current Status

This PR is still draft. The foundation slices are implemented and validated, but the card should not be called complete yet.

Still outstanding before Extract Pro is complete:

• Move the actual Organize feature source into a private @codegraphy/organize package/repo.
• Remove base/free extension ownership of Graph Sections, pins/collapse, and legacy graphLayout Organize behavior once the private plugin owns it.
• Wire and document the private Organize package quality-tool plan after the source move.

Validation

• pnpm run lint
• pnpm run test
• pnpm run build
• Focused red/green checks along the way for plugin API contracts, Core access/data hosts, Graph View runtime/projection/force/context-menu/UI slot behavior, Pro package, web app, MCP link command, and release contracts.
