Version the managed comment marker

[kitsuyui]

Summary

• bump the package version from 0.0.1 to 0.9.0 to match the current release line
• version the managed comment marker as <!-- happy-commit:v1 -->
• keep recognizing the legacy <!-- happy-commit --> marker so existing comments are updated or removed instead of being orphaned
• add tests covering legacy marker migration
• rebuild the generated dist output

Checks

• bun install --frozen-lockfile
• bun run format
• bun run lint
• bun run test
• bun run build
• git diff --check
• bunx madge --circular --extensions ts src/
