Hojun-Cho 3ee1906497 test: migrate Fam10 alias value tests to @test, carve divergences to pins (#5-C3)
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_b6_run — SLIM CARRIER (#5-C3 alias fold-2). The 23 K_RUN value
* rows migrated to test/lang/alias_cgen_b6_test.ww (@test, cs==ww byte-id); the
* symmetric K_BUILDERR rejects (fsarg0_loud_ctl, try_loud_38b) to
* test/wcc/data/alias_{fsarg0_loud,try_loud_38b}/case.ww runww.
*
* What survives here is the one IRREDUCIBLE Group-B row: BOTH stages reject the
* same input but with DIFFERENT diagnostics — a held cs!=ww divergence (a
* rule-10 smell, tracked not silently merged). A single-substring runww
* //ww:error would erase the distinction; this carrier asserts EACH stage's own
* substring. cstage rejects with the #271/#165 SSE-eightbyte-transport reason;
* wwstage rejects with the #272/#276/#277 aggregate-return scalar-default
* reason (the float-bearing alias struct arg from a non-ident source).
