feat(devins-lang): extract toolhub for variables #100

Added AgentToolOverviewCompletion for DevIns language code completion. Replaced AgentToolLibraryCompletion with new class to provide completions for agents and commands in DevIns language code. Added ToolHub enum to manage types of completions and customized completion behavior accordingly.
