Subject: [PATCH] fix(fileio): satisfy ABI layout lint

Use the type's bit width for the pointer-sized tail in the source-file
projection layout assertion.  This is numerically identical to eight
pointer-sized bytes on supported targets while keeping the assertion
compatible with the repository's warnings-as-errors lint policy.

Test Plan:
- ulimit -v 41943040; CARGO_BUILD_JOBS=1 cargo fmt --manifest-path rust/Cargo.toml --all -- --check
- ulimit -v 41943040; CARGO_BUILD_JOBS=1 cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings
