fix(ci): enable cross-OS cache sharing for Windows builds

Add enableCrossOsArchive: true to all WASM cache actions to allow Windows
runners to access caches created on Linux runners.

Root cause:
- build-wasm.yml runs on ubuntu-latest (Linux)
- Creates caches using Linux-specific compression
- build-sea.yml Linux/macOS jobs could access these caches
- build-sea.yml Windows jobs could NOT access Linux caches (OS-specific by default)

GitHub Actions caches are OS-specific unless explicitly configured for
cross-platform sharing. Windows requires enableCrossOsArchive: true to
access caches created on Linux/macOS runners.

Changes:
- build-wasm.yml: Add enableCrossOsArchive to Yoga, AI, ONNX caches
- build-sea.yml: Add enableCrossOsArchive to all three cache/restore actions

This allows Windows SEA builds to use WASM assets cached by Linux runners,
eliminating the cache miss errors that were causing Windows builds to fail.
