## Why
The `core` and `tui` Bazel targets treated nearly their entire crate trees as
compile-time data, mixing embedded runtime resources with source files and test
fixtures.
## What changed
- Move embedded resources for `core` and `tui` into dedicated `assets/`
directories and update their `include_str!` paths.
- Restrict Bazel compile data to explicit asset and frame directories.
- Move test-only prompts into `tests/fixtures`, resolve the core prompt through
`find_resource!`, and reuse the integration-test file glob when assembling
Bazel test data.
