The Architecture of a Transparent CLI Proxy

ContextZip is a transparent CLI proxy that wraps shell commands via a shell function approach, filtering output through a multi-stage pipeline (ANSI stripping, pattern detection, stack trace filtering, duplicate grouping, noise removal) without altering command behavior. Built in Rust for near-zero latency (<1ms), it guarantees exit code pass-through, separate stdout/stderr, and proper signal propagation.
