Update AGENTS.md to reflect current codebase structure

- Rename header from CLAUDE.md to AGENTS.md
- Add missing internal components (core-macros, common)
- Add missing backends (selector, testing)
- Add missing tools (slintpad, figma_import, tr-extractor, updater)
- Add wasm-interpreter API
- Add new Editor Support section with all editor integrations
