Move the advanced-CDict workspace-size formula and its by-reference,
by-copy, row-match-finder, and dedicated-search branches into the Rust
compression-parameter layer. Keep private C layout constants and the
already-resolved mode at the C boundary, where the allocator still owns
private object layout details.
Add a focused test covering the load-method and dedicated-search deltas
and the exported advanced-sizing boundary.
