fix(project): show fullscreen titles placed at the end of the video

[yashranaway]

a fullscreen title placed right where the video ends, like a closing card, makes the timeline longer, but there was no source frame to map that extra time to. playback and export both stop as soon as a frame has no source, so the closing title never showed up.

now a hold that starts at the very end falls back to the last source instant before the end, so the title plays over the final frame. normal end of timeline behavior is unchanged. tests cover multiple clips, speed changes, transitions and an empty timeline.

Confidence Score: 5/5

The PR appears safe to merge; no new actionable issues were found.

Summary

Closing fullscreen titles now hold the last instant of the final non-empty clip instead of relying on a rounded timeline time.

• Closing titles show over the final clip frame.
