BootZ: Introduce NetBoot module & consolidate STANDALONE macro

- Renamed __BOOTLDR_STANDALONE__ → __BOOTZ_STANDALONE__ across all modules.
- Introduced NetBoot module to support fallback booting via packets.
- Updated amd64-desktop build to bundle netboot.sys as part of system image.
- NetBoot now properly zeroes out its header and performs sanity check on PatchLength.
- Boot flow now attempts to fallback to NetBoot if neoskrnl.exe fails to start.
- Reorganized disk formatting logic for clarity and better failure recovery.
- HeFS & NeFS minimum disk size lowered (64GiB → 256MiB and 4GiB → 8MiB).
- Renamed `IndexProperty` to `Index` in FSKit::Indexer.
- Moved HintKit → hint/, updated includes and guards.
- Removed deprecated LPC.{cc,h}, replaced by ProcessCodes.h.
- Modernized SystemCalls.h typedefs: SCIObject → Ref, ThreadObject → ThreadRef, etc.
- Updated userland tools `make_app` and `open` with copyright and behavior fixes.

This prepares the BootZ infrastructure for headless/network environments.
