fix: force native tool mode for huly-mcp 0.44 compatibility

huly-mcp 0.44 defaults unknown clients (including this CLI) to a proxy
surface that only advertises meta-tools via tools/list, hiding the native
tools (get_issue, list_issues, ...) the CLI dispatches directly. Pin
@firfi/huly-mcp to 0.44.3 and force HULY_TOOL_MODE=native so every tool
stays first-class and the direct tool-name dispatch keeps working.
