Make repo fully path-portable and add reproducible installer

- install.sh: one-command fresh-Ubuntu reproduction (deps, NVIDIA clone
  + patch, GSP firmware fetch from linux-firmware.git with objcopy
  .fwimage extraction + MD5 verify, ordered build, host config, load,
  mdev creation). Wrapper-neutral: works with libvirt/raw QEMU.
- patches/nvidia: regenerated path-independent patch (KBUILD_EXTRA_SYMBOLS
  resolved via $(src)/$(CURDIR) relative to the NVIDIA tree).
- scripts/stack_manager.sh and helper scripts auto-detect repo root
  (OPEN_IOV_ROOT override); no hardcoded developer paths anywhere.
- firmware analysis scripts use script-relative paths (also fixes stale
  firmware/570-GSP references); docs/wiki updated to $OPEN_IOV_ROOT.
- .github/workflows/ci.yml updated for standalone repo layout; firmware
  fetched from linux-firmware in CI.
- Untrack remaining kbuild artifacts (Module.symvers, modules.order,
  *.o.d); gitignore them.
- STATE.md: live project state, limitations, fixed/open bugs.
- README.md: rewritten for clone-and-run reproducibility.
