fix: reset-conversation clears per-channel conversations in v2 store (#320)

The reset-conversation CLI command was reading/writing the agent JSON file directly, missing the per-channel conversations map introduced with conversation routing. Now uses Store.clearConversation() which clears both the legacy conversationId and all per-channel conversation keys.

Also adds multi-agent awareness: prompts which agent to reset when multiple agents are configured.

Closes #316
