test: port the M3 .wwi-consumer keystone to ww; retire 989_m3sep

m3sep_test.ww drives the raw w6c/w6a/w6l toolchains (+_ww twins) over
hand-composed //ww:module units splicing produced .wwi bytes: the
bodies==.wwi keystone on both stages per package (mid/root/smid) with
determinism, rule-10 and the value-global DATA guard; the end-to-end
i32 chain (exit 59) with final-exe byte-id; and the #49 str-label /
#53 export-leaf link legs (exits 160/140) with their .s needle
proofs. Each @test re-produces its .wwi cold instead of sharing the
carrier's single scratch dir (same claims, sharper isolation).

package m3sep_test;
// M3 `.wwi` separate-compilation CONSUMER gate (task #22 arc). Port of
// the retired native carrier test/wcc/989_m3sep_run.c; every assertion
// preserved. Drives the raw w6c/w6a/w6l toolchains (+_ww twins), never
// the ww driver: the composed //ww:module units splice PRODUCED .wwi
// bytes between compile steps — an inter-stage artifact flow no
// driver invocation or fixture can express.
//
// keystone (rob §4.1, the load-bearing claim) — compiling package P
// under `-c` with deps as `.wwi` emits byte-identical codegen to deps
// as full BODIES, holding the -c filter constant and varying only the
// dep-source form; proven per package (mid, root, smid) on BOTH
// stages (a wwstage-only guard regression cannot hide behind the
// .wwi-sourced sep unit), plus cs==ww on the sep unit (rule 10),
// sep-path determinism (same input twice -> identical), and the
// value-global guard: an imported `export let` must never re-emit its
// DATA[W] definition (link collision). The smid row exercises the
// strlit-intern guard: neutralize it and sleaf.banner interns ahead
// of smid.label in the bodies-unit, desyncing `_S_` -> keystone RED.
//
// chain — end-to-end: leaf/mid/root compiled -c, assembled, linked
// with libwwrt.a and RUN through both full toolchains -> exit 59 (the
// real cross-boundary computation over all four fact-classes: fn
// signature, struct layout, def const, export-let global); the two
// final executables byte-identical (rule 10 end-to-end).
//
// str49 (#49) — two str-bearing packages sep-LINK without an `_S_`
// label collision (per-unit prefix): exit 160 reads a distinguishing
// byte THROUGH each str's .ptr; cstage .s carries `sleaf._S_` /
// `smid._S_` and no bare `DATA _S_0(SB)`.
//
// leaf53 (#53) — two packages exporting the SAME-named non-fn leaves
// (`let v`, `def K`) sep-LINK because every exported decl
// path-qualifies (cea.v/ceb.v, cea.K/ceb.K, no bare v/K DATA): exit
// 140 proves each getter reads its OWN module's data.
//
// Dropped C machinery, not assertions: the ~70-entry remove_child
// cleanup ledger (testenv.clean asserts the recursive removal).

* 989_m3sep_run — M3 `.wwi` separate-compilation CONSUMER gate (task #22 arc).
*
* M3 = w6c `-c` (separate-compile / primary-only codegen) reads each imported
* package's `.wwi` prototypes (M2's producer output) as import scope INSTEAD of
* re-checking dep bodies. Since the sep flip this IS the sole compile
* path. This gate certifies the consumer.
*
* Fixture: a leaf -> mid -> root chain carrying ALL FOUR cross-boundary fact-
* classes — fn SIGNATURE (leaf.add), struct/type LAYOUT (leaf.Point, used as a
* by-value param + returned), `def` const VALUE (leaf.SCALE, const-folded into
* mid), and `export let` value-global (leaf.origin_tag, read across the
* boundary). mid imports leaf; root imports both.
*
* THE LOAD-BEARING CLAIM (rob §4.1): compiling package P in sep mode (deps as
* `.wwi`) produces the SAME codegen for P's own symbols as compiling P with
* deps as full BODIES — proven by holding the `-c` codegen FILTER constant and
* varying ONLY the dep-source form:
* Pbodies.s = w6c -c (deps as //ww:module body sections + P)
* Psep.s = w6c -c (deps as //ww:module .wwi sections + P)
* GATE: cmp Pbodies.s Psep.s → byte-identical (per-package, sharp blame).
* Both emit ONLY P's symbols (the `-c` filter), so the cmp proves the `.wwi`
* conveys exactly the type/layout/const facts the dep bodies did, for P's code.
*
* Plus, per package: the keystone on BOTH stages (cstage bodies==sep and
* wwstage bodies==sep — so a wwstage-only guard regression can't hide behind
* the `.wwi`-sourced sep unit), cs==ww at the `.s` level (rule 10 — w6c vs
* w6c_ww on the identical sep-unit), sep-path determinism (compile twice ->
* identical), and the value-global guard (an imported `export let` must NOT
* re-emit DATA — that would duplicate the dep's own definition -> link
* collision). A str sub-fixture (sleaf -> smid -> sroot) makes the strlit-
* intern guard non-vacuous AND, post-#49 (per-unit `_S_` prefix), LINKS the
* two str-bearing packages without a label collision — see its note below.
* End-to-end:
* compile each package's .o under `-c`, link with w6l, run -> exit code is the
* real cross-boundary computation; the SAME with the wwstage tools (w6c_ww/
* w6a_ww/w6l_ww) -> cs==ww at the final-exe level + behavioral identity.
*
* COLD: a fresh getpid-keyed /tmp dir, `.wwi` materialized from scratch every
* run (no warm cache — a stale `.wwi` is a #110-class freshness hazard). It
* writes nothing to the source tree. 9xx is full; shares the 989
* prefix per the 989_lib_byteid / 989_m2wwi precedent (the short name keys the
* binary). Models 989_m2wwi_run.c conventions.
