test: migrate global value r/w family-5 to test/lang @test, retire C twins (fold-2)

Browse Source 
Continue fold-2: migrate the global-value read/store/addr-of family (non-tagged)
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); the $(TESTS)
headline drops 3 (421->418). All asserts are primitive int comparisons; fresh
globals are zeroed, so a store that misses the symbol reads back 0 and FAILS.

  989_globptrfield_run.c  -> glob_ptr_field_test.ww  (scalar field store through a module-global *struct pointer loads the pointer from gp(SB), not saved BP; runtime gp=&backing form, static-init is #48-blocked)
  989_globstructret_run.c -> glob_struct_ret_test.ww (returning a module-global struct ident by value copies g's bytes; rsz 16 + rsz 24, each field asserted)
  989_dotbasehijack_run.c -> dotbase_hijack_test.ww  (indexing an [N]T field of a module-global struct addresses the struct field, not an unrelated global sharing the field name; +typed-inner control +colliding-global-intact pin)

glob_ptr_field keeps only the .c's offset-0 row: an added non-zero-offset row
(gp.g=9) surfaced a cs!=ww divergence (cstage folds the offset into the store
displacement `MOVQ AX,8(BX)`; wwstage emits `ADDQ $8,BX; MOVQ AX,(BX)`) — a
latent global-*struct-pointer field-store divergence beyond the .c's coverage,
reported for the backlog, not carried here. Bump LANGBYTEID_EXPECTED_MIN 35->38.

* THE BUG (cat-A silent miscompile, align-UP): cgenexpr.ww dotbaseaddr's

* the wrong symbol. cstage cg_dotbase_addr gates the #128b probe on
* inner->type == NULL || ty_err (cgen.c:2109 — a module qualifier has no

* THE FIX: gate the wwstage #128b probe on tichase(inner.type_) == nil ||

/*
* 989_globptrfield_run — inverse-set cstage fix (report-item [58], ww correct):

*
* THE BUG (cat-A divergence — cstage SEGV, wwstage correct): in cgen.c the
* N_DOT-lhs scalar field-store via_ptr arm loaded the base pointer with
* `MOVQ boff(BP),BX`. For a module-global `*struct` ident boff==0, so cstage
* emitted `MOVQ (BP),BX` — derefing the saved BP word as if it were the
* pointer → store through garbage → SEGV (rc=139). wwstage already loaded the
* pointer from the symbol (`LEAQ gp(SB),BX; MOVQ (BX),BX`) and ran correctly
* (rc=7). This is the INVERSE of the F8 #263 set: ww is the runtime-correct
* reference; the cstage half is filed as ww-core TASK #47.
*
* THE CSTAGE FIX (align cstage UP to ww): the via_ptr scalar store detects a
* global base (boff==0 && let_islet) and emits the ww-correct global-pointer
* load — PUSHQ AX; LEAQ gp(SB),BX; MOVQ (BX),BX; POPQ AX — before the store.
* Local bases keep the BP load (byte-id). Both stages now emit the identical
* .s and exit 7.
*
* The static-init form `let gp: *S = &backing;` is blocked on wwstage by a
* separate static-init-of-&global gap (ww-core TASK #48), so the repro uses
* the nil-init + runtime `gp = &backing` form, which builds on both stages.
