[FEAT] Re-implement "snooze" intent

[NeonDaniel]

Objective

Handle "snooze" requests in converse.

Initial Implementation Requirements

• Handle simple "snooze" vocab match with default duration
• Use extract_duration to handle requests to snooze for a specific duration
• Use extract_datetime to handle requests to snooze until a specific time

Other Considerations

Structure this so the logic at least can be unit tested
