ddidderr 2442fddc38 refactor(fileio): move separate-output routing policy to Rust
Move the separate-destination mode decision into the Rust file-iteration
boundary. The projection now carries the mirror-mode bit and one callback for
each destination policy, so Rust selects the callback once before preserving
the existing non-short-circuiting iteration and aggregate error behavior.

Keep path construction, mirror-directory diagnostics, resource ownership, and
the per-file compression leaf in the opaque C callbacks. Add C/Rust layout
assertions and focused tests proving mirror/flat routing and ordered error
aggregation.

Test Plan:
- `ulimit -v 41943040; cargo +nightly 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`
- `ulimit -v 41943040; CARGO_BUILD_JOBS=1 cargo test --manifest-path rust/Cargo.toml --all-targets` (793 tests)
- `ulimit -v 41943040; CARGO_BUILD_JOBS=1 cargo clippy --manifest-path rust/cli/Cargo.toml --all-targets -- -D warnings`
- `ulimit -v 41943040; CARGO_BUILD_JOBS=1 cargo test --manifest-path rust/cli/Cargo.toml --all-targets` (184 tests)
- `ulimit -v 41943040; make -j1`
- `ulimit -v 41943040; make -j1 -C tests test`
