refactor: namespace restructure of entire codebase

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
