Organize bundled Rust resources under asset directories (#41477)

## 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.
