continuous-integration/drone/push Build is passing
Reorganize all source files into a hierarchical namespace structure with dot-separated unit names matching directory paths. Major changes: - src/prog/ -> src/app/ (app.*.pas) - src/fault/ -> src/arch/x86/fault/ (arch.x86.fault.*.pas) - src/isr/ -> src/arch/x86/isr/ (arch.x86.isr.*.pas) - src/include/ -> src/core/ (core.*.pas) + src/arch/x86/ - src/driver/ subtree reorganized with driver.* namespace prefixes - src/driver/storage/con/ -> src/driver/storage/ctl/ (Windows reserved name fix) - src/driver/storage/ split into con(ctl)/fs/vol/ subdirectories - src/driver/net/ flattened from l1-l5 layers to driver.net.*.pas - kernel.pas -> asuro.pas, faults.pas -> arch.x86.faults.pas - stdio.pas/syslog.pas -> io/io.stdio.pas, io/io.syslog.pas - processmanager.pas -> proc/proc.mgr.pas - lmemorymanager.pas -> memory/memory.heap.pas - Build scripts moved to toolchain/ - Added compat/ shims for lmemorymanager and types - Added doc/namespace.md tracking the refactor 197 files changed, 6292 insertions(+), 5526 deletions(-)
