Automatically extract
.tgz,.tar.gz, and bzip2-compressed tar archives through a bounded streaming bridge, with staged validation and atomic commit semantics.The shared decoder output path now supports owned chunks, allowing bzip2 and gzip to use one scheduler without unnecessary copies. Gzip resolves only the marker prefix needed for ordered history, computes clean-suffix CRC work in parallel, and uses a finer speculative grid for better cadence. Isolated archive, cadence, memory, and full-wiki benchmarks cover the new paths.
README sections CLI, Performance, and Implementation and compatibility document user behavior and current results. DEV.md sections Archive extraction benchmarks and Local Wikipedia benchmarks contain the architecture, fixtures, exact commands, and rejected alternatives.
