feat(obisys): Add stage-based performance profiler

Establishes the `obisys` crate using Rust 2024 and the `libc` dependency. Introduces a lightweight profiler that captures wall-clock time and `getrusage` system metrics per pipeline stage. Automatically computes parallelism and efficiency ratios, detects bottlenecks such as memory pressure and disk I/O, and prints a formatted diagnostic summary to stderr.
