Fix netboot initialization and add documentation tooling

Browse Source 
- Add CLAUDE.md with project architecture and build documentation
- Add verify-image.sh script to validate generated netboot images
- Fix boot.ipxe kernel parameters:
  - Add boot=netboot to invoke custom initramfs script
  - Add console=tty0 for VGA output alongside serial console
  - Fix earlyprintk serial specification
- Remove dead symlink creation in build-image.sh (http/latest pointed to non-existent directory)

The boot=netboot parameter is critical - without it, initramfs falls back to local boot
and fails with /dev/root errors. The console changes enable viewing boot messages on
monitor instead of only serial port.
