Normalize agent name comparisons to handle display name keys

Hooks and tools now use getAgentConfigKey() to resolve agent names (which may
be display names like 'Atlas (Plan Executor)') to lowercase config keys
before comparison.

- session-utils: orchestrator check uses getAgentConfigKey
- atlas event-handler: boulder agent matching uses config keys
- category-skill-reminder: target agent check uses config keys
- todo-continuation-enforcer: skipAgents comparison normalized
- subagent-resolver: resolves 'metis' -> 'Metis (Plan Consultant)' for lookup
