Summary
all_fileslimited to the Rust sysrootMotivation
Every Rust compilation currently inherits the complete C++ toolchain file set, including compiler headers and unrelated SDK libraries. Linking actions already declare their linker and runtime inputs separately, so carrying the full C++ toolchain through every action unnecessarily expands action inputs.
