pub fn deduplicate_params_in_slice(slice: &mut StubSlice)Expand description
Deduplicate parameter lists across all methods and functions in a StubSlice.
Many PHP framework methods share identical parameter lists (e.g., thousands
of (string $arg, array $opts) signatures). This function groups identical
param lists globally (across all slices processed so far) and replaces them
with Arc<FnParam> pointers to shared allocations.
Expected memory savings: 100–150 MiB on cold start (vendor collection).
