`gpui_harness_tests.rs` was the repo's largest file (1062 lines) and the
worst violator of the 500-line / no-god-component audit. Its 13
`#[gpui::test]`s each build their own local fixtures and share only a
pair of type aliases, an `impl super::ElyShell` test helper, and two free
fns (`active_tab_overlay_state`, `example_url`).
Keep those shared items plus tests 1-4 in the root module; move tests 5-8
to `gpui_harness_tests_b.rs` and tests 9-13 to `gpui_harness_tests_c.rs`,
each opening with `use super::*;` so they inherit the parent's imports
and shared items with no per-item churn. Declared via `#[path]` mod, the
established sibling-test pattern in this crate.
475 / 319 / 276 lines. No tests added, removed, or renamed (paths gain a
`gpui_harness_tests_{b,c}::` segment). clippy --all-targets -D warnings
clean; `cargo test -p ely_app` 167 passed / 0 failed.
