Previously, Vitest UI opened the trace view UI for any test selected in a file when traceView is enabled. However, with traceView.mode: 'failure-only' being the default, selecting any passing test with no artifacts ended up opening an empty pane with "No trace found". The editor also reserved an empty trace marker column for the same case.

This PR fixes it by triggering trace view UI features based on whether the test has trace artifacts instead of the global traceView config.

fix(ui): open trace view only for tests with a trace
bc5ded3 
In `failure-only` mode only failed tests record a trace, but selecting any
test in a trace-enabled file auto-opened an empty trace view. Open it only
when the test has a trace in that mode. `on` mode still opens it before
steps arrive so a running test streams live.

refactor(ui): show trace gutter only while a trace is open
efdf673 
Decide trace view from recorded traces, or `on` mode for live streaming,
and drop the file-level config check. The editor's trace gutter now
follows the open trace instead of the config, so a file with no trace
doesn't reserve an empty column.
