fix: fix missing initialSyncDepth logic

TerrorJack · Codex · TerrorJack · commit 6671ac48666b · 2025-11-28T20:49:21.000+01:00
This patch declares initialSyncDepth (and ensure syncDepth is
initialized) in the wasm inlined JS runner so nested sync callbacks
start with the correct depth. Do the same in the standalone
jsaddleScript used for workers, keeping both entry points aligned with
upstream JSaddle changes. Fixes the runtime ReferenceError that broke
TodoMVC after updating jsaddle to the latest upstream.
