test: migrate dotfield/idxfield compound-assign to @test + runww rejects, retire C twins (fold-3)

Browse Source 
949_dotfield_compound + 949_idxfield_compound are one bug class (#133-lineage compound-assign load-op-store on field lvalues; #34/#33, #263 carve-out) sharing the combine + hard-error path, so the two C carriers fuse into one commit: 26 value rows -> test/lang @test row-tables (primitive-only asserts), 8 reject rows -> runww //ww:error dual-stage carriers. byteid floor 50->52.

/*
* 949_dotfield_compound_run — runtime + byte-id net for #34 (#263 both-
* stages): a compound assign on a single-dot field lvalue
* (`s.f OP= v`, `p.f OP= v`, `g.f OP= v`, `sl.len OP= v`) must do a real
* LOAD-OP-STORE for ALL ten integer ops, not silently demote any op
* other than += / -= to a plain `s.f = rhs`.
*
* Pre-fix: every single-dot field-compound arm in BOTH stages wired only
* PLUSEQ/MINUSEQ; *= /= %= &= |= ^= <<= >>= left the old value in BX and
* the rhs in AX, then fell into the generic store of AX — `s.f *= 3`
* silently compiled to `s.f = 3` (gate-blind, .s byte-identical). The
* five sub-arms (via-ptr-base local, direct struct local, str/slice
* pseudo-field, global struct field) all shared the BX=old/AX=rhs
* convention; the fix routes every one through one shared combine helper
* (cgdotfieldcombine / cg_dotfield_combine) wiring all 10 ops and
* hard-errors float/str/slice/tagged fields LOUD (rule-7). cs/ww move
* together (#263 carve-out); byte-id witnesses rule-10.
*
* Each row carries (a) a cstage `ww build` + run asserting the exit code
* and (b) a w6c vs w6c_ww `.s` cmp (rule-10 byte-id). builderr rows
* assert BOTH stages fail loud with the cited diagnostic substring.
