release: package relocatable Linux SYCL archives

[Jsewill]

Package Linux x86-64 SYCL archives for NVIDIA, AMD, and Intel with relocatable AdaptiveCpp/JIT runtimes, explicit compiler and GPU targets, dependency licenses, source/toolchain metadata, and SHA-256 checksums. Reuse AdaptiveCpp deployment support and keep system drivers outside the archives. Tagged builds create draft releases for hardware qualification.

Supporting fixes keep CPU-only multiworker batches out of GPU budget queries, include actual streaming overflow capacity in VRAM admission, and remove an unused production CLVM dependency from key generation. The Windows evaluation documents the remaining upstream toolchain, backend memory-query, and hardware qualification gaps for AMD and Intel.

Validation:

• All three GitHub-hosted release builds passed host tests, clean Ubuntu 24.04 runtime/JIT checks, CPU plotting, and full proofs.
• The exact hosted NVIDIA archive passed 54 CPU byte comparisons across k=18–28 and every tier/spill variant, each with 100 full-proof challenges.
• The exact hosted Intel archive, using the documented B580 driver settings and a 1024 MiB VRAM margin, passed 14 cases covering every k=22 tier/spill variant and k=28 plain plus disk variants, each with CPU byte comparisons and 100 full-proof challenges.
• A targeted NVIDIA k=28 Compute Sanitizer initcheck reported zero errors; the instrumented output matched the retained CPU reference and passed 100 full-proof challenges.
• Both hosted archives passed real CLI cancellation, key-preserving resume, publication failure/recovery, and parallel CPU plotting.

AMD hardware was unavailable. An initial locally built NVIDIA archive produced one k=28 byte mismatch, and initial Intel parallel queue tests hung; neither issue recurred in subsequent qualification, but their causes remain unresolved. Keep this draft until those findings and remaining hardware coverage are accepted for release.
