History
agra df2ccf77bd issue-0038 fixed: closure capture through FfiIntrinsicCall args 
`collectCaptures` in `src/ir/lower.zig` was the closure free-variable
analyzer that decides which names from a closure body need to be
boxed into the env struct at lambda-build time. Its switch on AST
node kind enumerated every other shape (`.call`, `.if_expr`,
`.match_expr`, `.for_expr`, etc.) but no arm for `.ffi_intrinsic_call`,
so the trailing `else => {}` quietly dropped its `args[]` and
`return_type` walks. Names referenced inside `#objc_call(T)(recv,
"sel:", ...)` from a closure body never made it into the captures
list, so when lowering bound the closure scope from env, those names
came back as "unresolved".

The fix adds the missing arm — walk `return_type` and every `args[i]`
the same way `.call` walks `callee` + `args`.

Companion changes:
- `examples/issue-0038.sx` → `examples/103-ffi-closure-capture.sx`
  (out of the open-issue namespace; comment header tightened to
  describe the feature, not the historical bug).
- `examples/ffi-objc-call-09-in-construct.sx` drops the
  `g_hasher_recv` module-global workaround that was added for this
  bug — the closure now captures `recv` from `make_hasher`'s arg
  list normally.
