design-b D-1a: retire the legacy-shim ablation builds + redundancy pins

Browse source 
Doc 20 D-1 (legacy runtime deletion), first slice: races_test_noheal /
races_test_nosleepfix pinned behavior of the legacy handlesleep shim,
which is being deleted — the pins now assert properties of a runtime
that no longer exists. Drops the two Makefile.wasm link+inject variants
(SHIM_DISABLE_TRAMPOLINE_HEAL / SHIM_DISABLE_HANDLESLEEP), the
shim-redundancy pin specs in asyncify-races.spec.ts, and resolves the
tests/README.md open task. The green battery still runs every scenario
against the scheduler glue.

## Open tasks
- **Research: are the Asyncify fiber shims still needed under native-EH?** Two
`scripts/common/inject-dyncall-shims.sh` fixes — the fiber trampoline self-heal
(§3c) and the nested-Asyncify handleSleep save/restore (§3) — were written for the
legacy-EH *park-throw* model. Under native wasm-EH the top loop is a per-frame-yield
while-loop with no park-throw, so ablating either shim
(`SHIM_DISABLE_TRAMPOLINE_HEAL` / `SHIM_DISABLE_HANDLESLEEP`, wired in
`tests/apps/Makefile.wasm`) no longer reproduces the disease it guarded — the old
red "ablation pins" in `asyncify/asyncify-races.spec.ts` have been flipped to
green "shim-redundancy pins" that now prove the native-EH path stays clean *with the
shim ablated*. **To do:** sweep the real apps (modals, nested fibers, long sleeps,
pthread pool) with each shim ablated; if all stay green, drop the shim injection and
these pins. Until proven, they stay injected (belt-and-suspenders).
- ~~Research: are the Asyncify fiber shims still needed under native-EH?~~
**Resolved at doc 20 D-1** (legacy-runtime deletion): the ablation builds
(`races_test_noheal` / `races_test_nosleepfix`) and their shim-redundancy pins in
`asyncify/asyncify-races.spec.ts` pinned a runtime that no longer exists — the
scheduler shim (`scripts/common/shims/asyncify-scheduler.js`) is the only runtime
and subsumes the handleSleep save/restore; the fiber trampoline self-heal (§3c)
remains injected unconditionally. The green battery runs every scenario against
the scheduler glue.
