This one needs environment variables set before it will start: CRUNCHER_TOOL_SET (Tool exposure tier: 'minimal' (5 tools), 'standard' (34 tools, default), or 'full' (43 tools)), CRUNCHER_TIMEOUT (Worker thread timeout in milliseconds for heavy calculations (default: 3000, range: 100-60000)). The author declared them in the registry entry; get the values from the project itself.
