* Refactor build rules in rules.mk to use a compile rule template for source files, improving maintainability and readability. Update dependency file generation to ensure correct paths. * refactor: move emscripten targets to rules.mk and fix build issues fix: correct .PHONY declaration and dependency handling in rules.mk
