Closes the two residual silent holes in the unknown-type diagnostic: - Nested closure / function bodies. The body walk stopped at closure and nested-fn boundaries, so a typo'd type in a closure's local annotation silently became a 0-field struct. `walkBodyTypes` now descends control flow and expressions to re-enter each closure / nested fn via `checkScope`, which accumulates that scope's generic + value-`Type` params onto the parent's — so an inner closure still sees the outer function's `$T` (no false positive) while a genuine unknown is flagged at any nesting depth. `harvestScopeDecls` collects type-decl names across the whole body (including nested scopes) up front so locals are never false-flagged. - Cast targets. `cast(T)` where `T` is a value-`Type` param (no `$`) cast to a fabricated empty struct silently; it now gets the tailored `$T` hint. An unknown *literal* cast target already errors via value resolution, so it's left to that path — no double diagnostic. Suite: 350 passed, 0 failed. Regressions: examples/1114 (nested-closure annotation), 1115 (cast value param).
