Fix MoonBit nightly warnings

[myfreess]

Summary

• Fix 121 nightly [0079] implicit_impl_as_method warnings from Community Cakes dashboard run Update deps #128.
• Add exactly 121 explicit pub extend Type with Trait::{...} declarations across the affected parser packages.
• Preserve the existing dot-method surface without editing generated parser sources.
• Regenerate only already-tracked package interfaces; changes are additive.

Validation

Using moon 0.1.20260815 / moonc v0.10.8+ab524e6b4-nightly, MOON_IGNORE_PREBUILD=1 MOON_WORK=off, and NODE_OPTIONS=--max-old-space-size=4096 for tests:

• moon check --target <wasm|wasm-gc|js|native> --deny-warn passed
• Tests passed: wasm 2586/2586, wasm-gc 2583/2583, js 2583/2583, native 2588/2588
• moon fmt, moon info, and git diff --check passed

The native build emitted one GCC warning inside the vendored async C dependency about posix_spawn_file_actions_addchdir_np; it is not a MoonBit diagnostic and the build/test exited successfully.
