chore: validate MoonBit 0.10.11 compatibility

[brickfrog]

Changes

• Correct the documented consumer import from brickfrog/tempo/src to the generated package name, brickfrog/tempo.
• Apply the formatting from MoonBit 0.10.11.

Reproduced consumer error

The documented import failed with Cannot find import 'brickfrog/tempo/src' in brickfrog/tempo/cmd/upgrade_smoke@0.8.1. The generated interface declares package "brickfrog/tempo". The corrected import compiled and ran.

Verification

• moon check --deny-warn --target all passed.
• Tests passed with 297 tests on each available target: wasm, wasm-gc, JavaScript, and native.
• Native release tests passed: 297. The native release build passed.
• The consumer smoke program produced the four required lines on wasm, wasm-gc, JavaScript, and native.
• moon info produced no interface change. moon fmt --check passed.
• LLVM was not verifiable with the stable 0.10.11 toolchain. Moon reported that LLVM is experimental and nightly-only, then failed with Sys_error("/home/justin/.moon/lib/core/_build/llvm/release/bundle/prelude/prelude.mi: No such file or directory").

Release decision

No release while the declared LLVM target remains unverified. The import correction is consumer-visible, but package release policy requires verification of every declared target.
