design-b D-1b: delete the legacy handlesleep runtime from the injector

Browse source 
Doc 20 D-1, second slice: the injector now injects asyncify-scheduler.js
unconditionally — the WX_SCHEDULER=0 legacy opt-out, the
SHIM_DISABLE_HANDLESLEEP ablation skip, and the
SHIM_DISABLE_TRAMPOLINE_HEAL ablation skip are gone, and
scripts/common/shims/handlesleep.js is deleted (the scheduler subsumed
its capture/restore, fiber guard, and trampoline-heal duties in S2).
Comment-only scrubs point the remaining references at the scheduler
shim. .ci-cache-epoch bumped (shim/injector behavior changed).
