refactor(make): reorganize targets and improve locking mechanism

1.	Introduce a “project lock” mechanism alongside the existing “build lock”; the lock file is now generated within the platform-specific Makefile.
2.	Set `project` as the default Makefile goal for consistency.
3.	Remove the `standalone` target to improve compatibility, especially when invoked via `make -f`.
4.	Simplify target dependencies for better maintainability and clarity.
