refactor(cli): expose filename and buffer leaves from Rust

Browse Source 
Move the pure filename-collision, input/output-buffer construction, and
compressed-destination-name helpers to direct Rust-owned caller symbols.
Leave C responsible for diagnostics, filesystem resources, suffix-list policy,
and the surrounding file-processing orchestration.

Test Plan: Pending capped full verification after this atomic ABI cleanup.
