feat: add Alexander Roper to AUTHORS and expand embedding API documentation

- Add Alexander Roper to AUTHORS file with newline fix for Starbeamrainbowlabs entry
- Replace placeholder embedding API docs with full guide covering static/dynamic linking and source inclusion
- Update codebase line count from 5,000 to 7,000 lines in README and index
- Fix relative documentation links to absolute URLs in README
- Add CSS styling for preprocessor directive syntax highlighting
- Update Xcode project file references and CopyFiles build phase UUID
- Adjust delta_blue benchmark expected value from 7032700 to 14065400
- Improve markdown header detection regex in generate_docs.py to avoid matching #include
- Refactor metrics.py to exclude curly brace lines from code line counting
- Add TEST_HEADERS dependency to test object compilation in wren.mk
- Remove NULL parameter from runFile call in main.c
- Refactor vm.c to support WrenBindForeignClassFn callback and rename externalBindForeign to bindMethodFn
- Update vm.h to remove bindForeign parameter documentation and adjust runFile signature
