fix(semantic): hoist Annex B block-scoped function declarations to var scope In sloppy mode JavaScript, function declarations inside blocks (if, try, switch, {}) have Annex B.3.2.1 semantics: they create an implicit var-like binding in the enclosing function scope. The semantic analysis was not modeling this hoisting, which caused the mangler to assign conflicting names to block-scoped functions and outer var bindings. Fix: hoist plain (non-async, non-generator) function declarations from block scopes to the enclosing var scope during binding, using the same move_binding + set_symbol_scope_id + hoisting_variables pattern as var hoisting. This makes the mangler handle them naturally alongside other var-scope bindings, allowing name reuse from sibling scopes. Skipped for TypeScript sources (Annex B is a JavaScript-only spec).
