Step 5.1.A of the FFI plan (variadic heterogeneous type packs → generic `Into(Block)` impl). The eventual step-5.2 impl body will read `#insert build_block_convert($args, $R);` to emit a per-shape `__invoke` `callconv(.c)` trampoline + Block literal. 5.1.A pins the builder's expected output verbatim across three void-returning pack shapes (0, 1, 2 args) plus one non-void shape (`f64 -> s32`) that exercises the `return typed_fn(...)` branch. Today: 4× "unresolved 'build_block_convert'" diagnostics — the builder isn't in stdlib yet. The next commit adds it to `library/modules/std/objc_block.sx` and the test flips green. The per-position type names in the emitted source come from `type_name(args[i])`; the slice itself is `[]Type` flowing through the new-form variadic + bare-`$args` path that the recent issues-0048/0049/0050 fixes unblocked.
