Add travel category schema

[keepsloading]

Goal

Add a travel category schema for apps that understand trip preferences.

This should help Memact turn travel activity into user-readable Wiki entries that users can approve, edit, reject, or delete.

Context examples

Travel apps may know things like:

• preferred trip style
• preferred stay type
• budget range signals
• preferred transportation modes
• destination interests
• accessibility needs that the user explicitly chooses to store
• travel constraints
• past trip patterns

Work to do

• Define useful context fields for the travel category
• Add example raw app context dumps
• Add normalized context examples
• Add user-facing Wiki entry templates
• Mark sensitive or risky fields clearly
• Suggest category-level permissions apps should request
• Add tests for safe context shaping

Important product rule

Travel context can be sensitive. The schema should avoid storing precise location history by default and should prefer user-approved summaries.

Acceptance criteria

• Schema avoids precise location history as default memory
• Raw app input examples exist
• Normalized output examples exist
• Wiki entry examples are human-readable
• Tests cover at least one valid and one sensitive-location case
