fix(llm-skill): prompt tool call

- Renamed `build_skill_artifact_set` to `build_skill_bundle` for improved clarity in asset management.
- Updated references in `SkillManager` to reflect the new method name and ensure consistent handling of skill bundles.
- Added `AppAssetsAttrsInitializer` to `SandboxManager` to enhance asset initialization processes.
- Implemented output truncation in `SandboxBashTool` to manage long command outputs effectively.
