What's Changed

Features

• Shell completions: generate completions for bash, zsh, fish, and elvish
• Compiler executable paths: preserve full compiler executable path in compilation database; resolve bare executable filenames to absolute paths
• Install script: new scripts/install.sh with build-time INTERCEPT_LIBDIR validation, replacing manual setup
• DevContainer: introduce devcontainer for streamlined development environment

Bug Fixes

• fix: inline va_arg extraction in variadic exec shims for i686 compatibility
• fix: preserve co-resident LD_PRELOAD libraries during env doctoring
• fix: restore session env vars in system()/popen() for older glibc
• fix: unify preload restoration for system()/popen() with exec-family doctoring
• fix: recover from poisoned mutex in popen/pclose instead of panicking
• fix: replace panic with TryFrom error for empty Execution arguments
• fix: return fmt::Error instead of panicking in Configuration Display impl
• fix: handle Prefix flags with = in name in build-time codegen

Robustness & Stability

• Replace multiple panic!/unwrap paths with proper error handling (thiserror, TryFrom, fmt::Error)
• Reimplement system()/popen() on top of posix_spawnp for safer process creation
• Add hardened interception tests for environment sabotage scenarios
• Replace serde_yml with serde-saphyr for YAML parsing

Compiler Recognition Overhaul

• Move compiler flag definitions from Rust source to YAML with build-time code generation
• Replace per-compiler interpreter structs with a generic FlagBasedInterpreter
• Auto-generate recognition patterns and ignored-executable lists from YAML schema
• Match ignored executables by filename instead of full path

Documentation

• Expanded README with usage guidance, platform info, and limitations
• Improved INSTALL with prerequisites, package manager instructions, and verification steps
• Improved CONTRIBUTING with developer workflow and guidelines

Internal Refactoring

• Split config.rs, infrastructure.rs into module directories
• Split output module (formats.rs, writers.rs) into focused submodules
• Centralize envp traversal into envp_iter iterator; consolidate session context
• Replace empty-string sentinels with Option<String>
• Extensive new test coverage across output, compiler interpreter, and interception modules

New Contributors

• @DarthGandalf made their first contribution in #676
