test: migrate Fam10 alias value tests to @test, carve divergences to pins (#5-C3)

Browse Source 
fold-2 chunk C3 (drew's Fam8-13 plan): 8 alias value-row C drivers, 205 rows
re-homed with zero loss -- 177 value -> 8 test/lang/alias_*_test.ww @test
row-tables; 16 reject -> runww //ww:error carriers (both stages reject);
3 cs!=ww value rows -> 2 *_runonly_test.ww (T1, byte-id-excluded, #60/#81);
9 irreducible asymmetric rows -> slim C pins, each ticket-cited and
mutation-proven non-vacuous:
  - accept amplen1/2,ampcap2: cs runs / ww rejects 'unsupported address-of
    shape' (#96)
  - cgen_b5 g73_heapfill: cs!=ww .s + ww link-fails on self-contained alloc;
    compile-smoke pin (#24)
  - cgen_b6 fsarg2_bound: both reject, different msgs, each vs the correct
    stage (#271/#165 cs vs #272/#276/#277 ww)
  - emit_b7 slc/slcstr/slctag _2lvl + slc_plain_ctl: slice-literal static-init
    divergence (#120/#29-kin, ken-d2-oracle)
4 fully-migrated drivers deleted, 4 slimmed-in-place to hold only the
irreducible pins. LANGBYTEID floor 74->82 (8 new byte-id @test files); test
count 388->384 (4 deleted; 4 slimmed kept). do-not-auto-batch files not in
Fam10.

/*
* 944_alias_cgen_b5_run — #5 alias arc F2b (B5 train): cstage cgen
* helper + funnel internalization through type_chase_named (c1), the
* #73 tripwire graduation (c2), the #89 cgreturn return-position widen
* (c3) and the #93 deref-index pointee chase (c4). All cs-only: every
* graduation is a DIVERGE→byte-id flip (cs aligns UP to ww's already-
* chasing asm); zero selfhost/lib bytes move across the train, so the
* _ww binaries stay bit-identical (the crossing detector).
* 944_alias_cgen_b5_run — SLIM CARRIER (#5-C3 alias fold-2). The 27 K_RUN value
* rows migrated to test/lang/alias_cgen_b5_test.ww (@test, cs==ww byte-id); the
* symmetric K_BUILDERR rejects (fill0_ctl, fill2_loud, g73_static_str) to
* test/wcc/data/alias_{fill0_ctl,fill2_loud,g73_static_str}/case.ww runww.
*
* Row sources are ken's B5 oracle probes (/tmp/ken_b5/src,
* .ai/ken-b5-oracle.md + its c1-BOUNDARY ADDENDUM) and the c3/c4
* seeds (/tmp/ken_na, kb4).

* ---- c4 (#93: deref-index pointee chase, #263-polarity) --------
* g93_l2_local | `(*p)[2]` over *arr2 (arr2=arr= |
* | [3]int) — cs emitted ONE spurious |
* | MOVQ (AX),AX (pointee ARRAY skip |
* | missed at 2 levels), SEGV 139; ww |
* | was the runtime-correct side | 0/0
* g93_def | def twin: `(*p)[2]` over &D, D a |
* | 2-lvl alias def array (kb5_def93) | 0/0
* g93_1lvl_ctl | 1-level pointee control — held 0/0 |
* | byte-id throughout | 0/0
*
* K_RUN rows build+run BOTH drivers (cs exit==cswant, ww exit==wwwant)
* and assert cstage/wwstage asm byte-id. K_RUN_NOID asserts both run
* cells but waives byte-id — cite the blocking task/commit at the row.
* K_CSERR_WWRUN is the dual-cell bound kind (the inverse of
* 944_alias_accept_run's K_RUN_CS_WWERR): the cstage build must FAIL
* with experr AND the wwstage build+run must exit wwwant — both cells
* asserted so neither the cs loudness nor the ww behavior can drift
* silently while the cited task is parked. NNN<950, self-contained
* /tmp sources, no imports (944 precedent).
* What survives here is the one IRREDUCIBLE K_COMPILES row: both stages
* FRONTEND-compile (w6c / w6c_ww → .s, rc 0) but the asm diverges (the ww
* deref-field READ carries the #24 field(SB) leak) so run + byte-id cells are
* unavailable, and a full `ww build` can't link this self-contained `alloc()`
* case (no rt malloc) — runww //ww:compile links and so cannot host it. The
* pin is the ABSENCE of the pre-c2 cstage #73 fatal at the heap struct-lit
* str-arm fill; the ww-side leak rides task #24. Compile-smoke only.
