feat(component2json, wassette): normalize WIT function name to be compatible with MCP Tool name (#57)

This commit normalizes the WIT exported function name to be compatible with MCP Tool name,
which requires the name to be of the form '^[a-zA-Z0-9-_]' and thus any non-alphanumeric
characters are replaced with a "_".
