fix(athena): use getAgentConfigKey for keyword-detector Athena exclusion

The previous check used currentAgent?.toLowerCase() === 'athena' which failed

after display name remapping stored the agent as 'Athena (Council)' in session

state. Now uses getAgentConfigKey() to resolve display names back to config keys,

matching the established pattern used by other hooks (atlas, todo-continuation, etc.).
