33 codegen↔runtime call-signature mismatches on native targets (found by runtime_abi_check.py) #11408

scripts/runtime_abi_check.py (#11398) compares every runtime declaration, call site, pending declare and NativeModSig row in perry-codegen against the runtime's real #[no_mangle] extern "C" signature. Besides the wasm32 worklist, it reports 33 mismatches that are wrong on native targets today:

• class (float vs int/pointer): the value travels in the wrong register class (xmm vs gpr), so the callee reads garbage.
• width: upper bits are undefined.
• arity: the callee reads unset argument registers.

Hand-verified examples:

• js_typed_feedback_array_set_index_or_string (perry-codegen/src/expr/index_set.rs:912) passes 4 args; the runtime reads a 5th, strict: i32.
• js_is_truthy is declared returning i64 at lower_call/native/native_ui_appshell_branch.rs:159, but it returns i32.
• The js_lodash_pad*/trim*/random declarations are one parameter short.
• js_json_get_bool / js_http_request_has_header / js_cheerio_selection_is are declared double over a bool return.

Caveat for native_table arity rows: the dispatcher pads to the table's arity and appends extra JS arguments, so such a row is a live bug only for calls that omit the runtime's extra parameters.

Reproduce: python3 scripts/runtime_abi_check.py --list class (and width, arity). Once these are fixed, those three categories can become a ratchet.
