## Stack Context
This PR is the API test coverage slice in the experimental personal
skills stack. The storage, schema, permissions, API, and SDK
implementation merged in #25363.
Stack order:
1. #25362 personal skill resolver
2. #25363 storage, permissions, API, and SDK
3. #25365 API test coverage
4. #25366 chattool and chatd integration
5. #25066 settings UI and docs
6. #25386 personal skills slash menu
## What?
Adds API and audit tests for personal skill CRUD, validation failures,
limits, authorization, soft-delete cleanup, and audit content tracking.
This PR is now test-only. It does not include migrations, generated
database code, or API implementation changes.
## Why?
The feature touches storage, permissions, and audit behavior. These
tests make the server behavior reviewable and protected without
re-reviewing the implementation that already merged in #25363.
## Validation
