fix: Synchronize MODULE.bazel tool versions with tool_versions.bzl

Critical fix aligning MODULE.bazel extension.register() calls with the
canonical versions in toolchains/tool_versions.bzl:

- wasm_tools: 1.241.2 → 1.243.0
- wkg: 0.12.0 → 0.13.0
- wasi_sdk: 27 → 29
- wizer: 9.0.0 → 10.0.0
- wasmtime: 37.0.2 → 39.0.1

This mismatch was causing:
- Weekly checksum update failures (Issues #229, #213)
- Build pipeline failures
- Version validation errors in tests

All extension registrations now match the upgraded toolchain from PR #240.
