AI Summary: Users are encountering assembly errors when attempting to build `main.ASM` and `sumpow.ASM` together from the `examples/linker/` directory on the `integration/macros-assembler` branch. The issue occurs after selecting both files in the GUI and clicking 'Build'. The reporter suspects the `.ASM` files themselves may be incorrect, leading to the assembly failures.

AI Summary: The application's "loader" component prevents users from performing more than one build consecutively. To initiate a new build, users are forced to close and reopen the entire application, indicating a problem with the loader's state management or resource release after a build completes.

AI Summary: The `assembler_test.ASM` example program is executing incorrectly. Although the step-by-step execution visually appears to perform the correct operations, the values stored at memory addresses defined by labels are ultimately incorrect. Steps to reproduce the issue are provided.

AI Summary: The linker is incorrectly generating `.OBJ` and `.meta` files as its final output, instead of the required single `.HPX` file. An error message further indicates a bug in the linker's output naming, as it attempts to save files with a `.HPX.obj` extension. The task is to modify the linker to exclusively produce the `.HPX` file.
