Hojun-Cho 438efab8c6 test: migrate str/slice global family-1 batch to test/lang @test, retire C twins (fold-2) ...

Continue fold-2 (after 374e97b): migrate the remaining Family-1 str/slice
global + literal + index + call-arg group from bespoke build+run C twins to
test/lang @test, retiring each twin in the same commit. Runtime coverage MOVES
from $(TESTS) to test-lang (T1 runs+asserts via `ww test`) + test-lang-byteid
(T2 keeps cs==ww .s byte-id); coverage is preserved, the $(TESTS) headline
drops 9 (434->425). All asserts are primitive int/u8/bool comparisons (no
fmt/strconv in the assert path); the slice-store/index rows reset the global
each fn and sum ADJACENT elements so a dropped/mis-strided/over-wide word FAILS.

  989_globslicefield_run.c    -> glob_slice_field_test.ww     (slice field of a global struct: g.f=<slice> stores full 24B header; len/cap/non-zero-offset + str/scalar controls)
  989_globstrslice_run.c      -> glob_str_slice_arg_test.ww   (global str sliced with default hi passed as call arg loads its len word; explicit-hi control)
  989_trystr_run.c            -> try_str_unwrap_test.ww       (`!` unwrap of str-success tagged union shuffles the str header for ident-source/error-first/success-first)
  797_len_strglobal_run.c     -> len_str_global_test.ww       (len(str-global) loads .len via name(SB); local-str control)
  801_litstr_pseudo_run.c     -> lit_str_pseudo_test.ww       (string-literal .len/.ptr pseudo-field; empty/multibyte + arg-passthrough)
  803_globalidx_run.c         -> global_index_test.ww         (global str/slice index read/addr-of/store/compound, esz 1/4; local regression pins)
  903_tuple_elem_slice_len.c  -> tuple_elem_slice_len_test.ww (len(t.N) of a slice/str tuple element loads .len at +8; 2/3-slice, str-slice both orders)
  927_composite_call_arg_run.c-> composite_call_arg_test.ww   (slice-returning CALL passed inline as a composite arg; canonical/letslice/two-call/middle/nested/scalar/tagged)
  952_slicecopy_assign_run.c  -> slice_copy_assign_test.ww    (bulk slice-copy-assign `arr[lo:hi]=bs`, esz 1/4, field/via-ptr/local bases; reslice-read companion)

rd_reslice asserts the TRUE value 360 (the .c twin's want=104 was 360 & 0xFF,
an exit-code truncation). 723_composite_call_arg.c's comment repointed to the
new test/lang location. 802_lenidx_run.c is DEFERRED (it carries //ww:error
reject rows — needs a value-rows-only split + a slim reject carrier, a fold-3
pass). Bump LANGBYTEID_EXPECTED_MIN 22->31 to ratchet the new corpus floor.
