test(flotilla): gate cancel test on Ray runner These flotilla-specific cancellation behaviors don't exist on the native runner, so the test only meaningfully runs under `DAFT_RUNNER=ray`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

perf: enable per-column compression configuration (#6884) ## Changes Made Adds per-column `column_compression` to the parquet writer so columns holding already-compressed payloads (JPEG/PNG/MP3/etc.) can opt out of codec work. ## Why? I was like, why are we compressing JPEG? We pay to compress JPEG with SNAPPY, then we pay to decompress SNAPPY. The simplest solution was allowing customers to specify per-column compression. Benchmarked snappy vs none on 10K JPEGs (`bytes` column, 70 MB output) with S3 moved out of the timed path, a discarded warmup, and 3 alternating iterations per mode in isolated subprocesses: | Metric | none | snappy | speedup | |---|---|---|---| | Wall time | 0.22s | 0.54s | **+142%** | | CPU user | 0.15s | 0.44s | **+205%** | | Output size | 70.66 MB | 70.15 MB | −0.7% | Snappy spends CPU compressing entropy-coded bytes that don't shrink. Skipping it is ~2.4× faster with no meaningful size penalty. This is a double benefit because we save on decompression as well. ## Related Issues n/a
