Module dispatch 

Shape-based lens dispatch.

Choosing a lens for a value is overload selection, which is exactly what the kernel Shape matcher already does. The dispatcher reuses that matcher and the documented resolution order; it is implemented once here and never reimplemented per domain. Resolution order (WEBUI_4 “Dispatch”):

1. explicit operator choice;
2. saved workspace preference;
3. best Shape match (most specific wins; ties by quality then cost);
4. class match fallback;
5. the universal default (always matches, lowest quality).

Every candidate must pass capability filtering; a denied lens is skipped and resolution falls through, ending at the read-only universal default.
