* refactor(ingestion): share callable declaration facts
Reuse pure parameter and signature facts between structure and scope
extraction, with tree-owned caches and read-only parameter contracts.
Preserve provider-specific wrappers and consumer projections.
Add characterization tests, real-worker parity checks, and reproducible
performance measurements. Keep the overall indexing effect explicit.
