fix(tool-config): remove erroneous global task permission deny

task: deny was mistakenly added to config.permission alongside the
council tool denials. This globally denied the task delegation tool
for all agents, overriding per-agent task: allow for sisyphus, atlas,
etc. Only council tools should be globally denied.
