Track: wit-bindgen MoonBit s8/s16 value corruption (upstream #1518)

[avrabe]

Upstream Issue

bytecodealliance/wit-bindgen#1518

Problem

wit-bindgen's MoonBit bindings corrupt s8 and s16 values during lift operations.

Impact on rules_wasm_component

• Affects moonbit_wasm_component rule
• Any WIT interface using s8 or s16 types will have incorrect values

Affected Rule

• //moonbit:defs.bzl - moonbit_wasm_component

Workaround

Use s32 or u32 instead of s8/s16 until upstream fix lands.

Action Items

• Add integration test to catch this regression
• Monitor upstream fix
• Update wit-bindgen when fix released
