fix(wasm-worker): remove duplicate paramBindings serialization in wasm-worker-entry (#1331)

paramBindings was serialized twice (lines 808 and 826 in the original code).
The second spread was a no-op since it overwrites the first with the same
value, but the duplicate caused confusion and was flagged in the Greptile
review as evidence of an incomplete field migration.
