The CCtx reset orchestration already runs in Rust, but its C workspace
adapter still decided when capacity was too small or wasteful and maintained
the oversized-duration counter through C-only predicates. Move those factor,
threshold, overflow, and duration-update rules into Rust. C now supplies only
private workspace metrics and retains low-level allocation, reservation, and
layout operations.
Remove the obsolete C predicates so the workspace resize decision has one
Rust-owned implementation and remains covered at its boundary conditions.
