Subject: [PATCH] Fix tests: render log frame grouping tests + blink test
 update

- All 6 render_log tests pass as plain #[test] (pure data logic)
- Fixed example_tests to use ExampleInputState (matching new API)
- Fixed blink test for focus-driven blink (test via typing, not init)
- Fixed test command in doc comment
- All 12 tests pass with: cargo test --example view_example -p gpui --features test-support
