.lumentis - balancing advanced features and sensitive data

[eugene-yaroslavtsev]

Problem

The .lumentis folder contains metadata necessary for advanced features like diff mode, but may also include sensitive transcript data that should not be committed.

Concerns

• Diff mode and other advanced features are must-haves
• Transcript data can be highly sensitive and should be protected
• The wizard is already lengthy, so adding more questions should be avoided

Tradeoffs

• committing full .lumentis data enables advanced features but risks exposing sensitive info
• excluding .lumentis entirely protects sensitive data but loses out on advanced features
• splitting .lumentis balances features and protection but requires careful implementation

Solution

We will split out sensitive parts of .lumentis folder and only commit the rest:

1. move input data out of .lumentis/wizard.json - .lumentis/sensitive-inputs/raw-data
2. move "questions for user to answer" data out as well - .lumentis/sensitive-inputs/clarifying-questions.md
3. add "no extra fields" zod validator for .lumentis/wizard.json to ensure the sensitive inputs can't accidentally end up in there
4. maybe add some docs (would be cool if there was some cool to do that)
