BREAKING CHANGE: Remove sendEmailWorkflow, add immediate processing to sendEmailTask

- Remove entire workflows directory and sendEmailWorkflow
- Factor out email processing logic into reusable utilities (emailProcessor.ts)
- Add processImmediately option to sendEmailTask input schema
- Update sendEmailTask to process emails immediately when requested
- Update processEmailsTask to use shared processing utilities
- Remove workflow-related exports and plugin configuration
- Simplify documentation to focus on unified task approach
- Export new email processing utilities (processEmailById, processAllEmails)
- Bump version to 0.4.0 (breaking change - workflows removed)

Migration: Use sendEmailTask with processImmediately: true instead of sendEmailWorkflow
