Add /extract-to-foundry slash command for shared code extraction

[jeffgo10]

Summary

Adds a new Cursor slash command (/extract-to-foundry) that guides agents through consolidating platform-agnostic utilities into @jeffgo10/* packages. The command includes a repo readiness gate, package placement rules, test/version bump workflow, and mandatory /create-github-pr follow-up after package edits.

Changes

Docs / Cursor rules / agent tooling

• Add .cursor/commands/extract-to-foundry.md with Audit, Implement, and Import & extract modes
• Step 0 repo gate: require clean master before package edits; auto-checkout when on a clean feature branch
• Placement table mapping canvas/image utils, gestures, layout types, and designer/upscaler packages
• Consumer app follow-up notes for CrowdBadge, LiteShadeMedia, and StickPak
• Document the new command in the README Cursor agent tooling table

Notes / follow-ups

None — docs/agent tooling only; no package version bumps or publish steps.
