big feat: custom cnn component

need a custom CNN to skim authorized emails, identify the keywords "Thank you for applying", and automatically fill out a new form.

How it will find the job posting applied to is undetermined.

The issue describes a custom CNN component for email processing, but the scope is undefined and the connection to job postings is undetermined. Start by examining the existing email handling and form-filling logic in the codebase to understand the data flow. Look for any existing machine learning or NLP modules to see how keywords are currently identified. 'Done' would be a working model that integrates with the application's email ingestion and form automation, but the design and implementation path are not specified.
