fix: fail loudly on missing NVIDIA libs and .ko, improve mknod logging

Browse Source 
build-nvidia-module.sh:
- Replace silent glob cp for libnvidia-ml/libcuda with find + explicit error
  if library not found in extract dir (catches installer layout changes)
- Fix circular symlink bug: don't create .so.1 -> .so.1 if versioned file
  is already named .so.1
- Verify .ko count > 0 after build, fail loudly if none produced
- Show lib cache in final summary

bee-nvidia:
- mknod failures are now logged with ewarn instead of silently suppressed
- If nvidia not in /proc/devices (no GPU hardware), log clearly and exit clean
