renacer 0.9.10

Pure Rust system call tracer with source-aware correlation for Rust binaries
Documentation
# Default Cluster Pack for Single-Shot Compile Workflows
#
# This file defines standard syscall clusters for transpilers/compilers.
# Users can override by creating project-specific renacer-clusters.toml
#
# Scientific Foundation:
# [3] Kuhn, A., Ducasse, S., & Gîrba, T. (2007). Semantic clustering:
#     Identifying topics in source code. IST, 49(3).
#
# Toyota Way Principle: Poka-Yoke (Error Proofing)
# - Configuration-driven: Add new syscalls without recompilation
# - Future-proof: Supports mmap3, clone3, and kernel evolution
# - Domain-extensible: Users can add GPU, ML, or custom clusters
