P10 (WIP): release build script, Dockerfile, conda recipes, fresh-VM acceptance task

scripts/build_dist.sh: sdist + pure wheel + manylinux_2_28 kernel wheels (maturin --zig,
both architectures). Dockerfile (multi-stage, kernels included, non-root user).
packaging/conda/{simurg,simurg-core}. scripts/p10/digest.py: platform-independent content
digests of GTC/VCF/summary outputs. Cloud task p10 installs the artifacts on a fresh
Ubuntu VM and runs the tutorial with pip, Docker and conda installs. trial.sh picks the
arm64/amd64 image from the instance type and can run instances in parallel (PARALLEL=1).
Licence files ship in both wheels; Rust crate notices added.

+simurg-core: optional compiled kernels of SimurgArray (MIT, see LICENSE).

+The kernels port numerics that SimurgArray's pure-Python modules port from gtc2vcf (MIT, (C) Giulio Genovese) and
+Illumina BeadArrayFiles (BSD-2-Clause, (C) 2020 Illumina); full notices: THIRD_PARTY_NOTICES.md of SimurgArray.
+The binary statically links PyO3, rust-numpy, ndarray and their dependencies (MIT / Apache-2.0 / BSD-2-Clause);
