v1.1.0

Added

• Criterion benchmarks for video pipeline operations (convert, resize,
  letterbox) covering 6 resolutions (640x480 through 3840x2160), 3 source
  formats (NV12, YUYV, RGBA), and 2 heap types (uncached, cached)
• On-demand CI benchmark workflow (bench.yml) on NXP i.MX 8M Plus with
  QuickChart.io summary charts and github-action-benchmark trend tracking
  on GitHub Pages
• Benchmark summary script (.github/scripts/benchmark_summary.py) parsing
  Criterion JSON data with fallback to bencher text output
• make bench target for running benchmarks
• Library scope sections in README.md and crates/g2d-sys/README.md clarifying
  user responsibility for cache management and buffer lifecycle
• TESTING.md documenting test infrastructure, DMA buffer implementation,
  on-target test execution, manual benchmark execution, and CI integration
  for both tests and benchmarks
• ARCHITECTURE.md documenting ABI compatibility handling
• GitHub Actions workflows for CI/CD
• SBOM generation and license compliance checking

Changed

• Moved to standalone repository (previously part of EdgeFirst HAL)
• Changed license from MIT to Apache-2.0 for consistency
• Updated to use workspace version inheritance
• Added comprehensive documentation
• Benchmarks separated from tests into proper [[bench]] criterion targets
  with criterion = { version = "0.5", default-features = false }
• Reframed DMA-buf cache coherency documentation as standard Linux protocol
  rather than platform-specific workaround
• DRM PRIME import is now step 1 of the cache coherency protocol in
  ARCHITECTURE.md, presented as a required part of correct DMA-buf usage
• All tests now use DMA-buf exclusively (no more g2d_alloc test buffers)
• Clear tests are now parameterized by heap type (_uncached / _cached)
• Release workflow uses OIDC trusted publishing instead of stored token

Removed

• Hand-rolled measure() timing helper and bench_* test functions
  (superseded by criterion benchmarks)
• fill() method — g2d_clear() works directly on DMA-buf buffers with
  proper DRM PRIME attachment; the blit-based workaround is no longer needed
• G2DAllocBuffer test infrastructure and create_g2d_alloc_surface() helper
• "Known Limitations" section from TESTING.md (g2d_clear/DMA-buf limitation
  was a cache coherency symptom, not a fundamental limitation)
