Miguel Ángel 81f60dbc98 fix(producer): exports no longer fail on a video clip outside the composition's length (#5431)
* fix(engine): exports no longer fail on a video clip outside the composition's length

A clip that starts at or after the composition's end (or ends before 0) is
never on screen, so extraction skips it. Its timeline window stayed as
authored, so the frame-coverage gate still expected its full length and
aborted the render with "captured 0 of expected N frames". Such a clip now
leaves extraction with an empty window, the same way a partly visible clip
is already trimmed to its visible part, so it owes no frames.

* fix(producer): drop clips outside the timeline before extraction, cloud renders included

The previous commit marked such a clip with end = start, but the window
resolver reads a zero-length slot as "use the source's natural length", and
the distributed plan still required an extracted entry for every declared
clip. Instead, the extract stage (shared by in-process and distributed
renders) removes clips that lie entirely outside [0, duration) from the
composition before probing and extraction, using one engine predicate that
the extractor's own early skip also uses, so a clip ending before 0 is no
longer downloaded or probed either.

* fix(engine): keep natural-length clips when dropping clips outside the timeline

A clip with no authored end carries end 0 (script-created media, or a src
set from a script), which the window resolver reads as "natural source
length". The outside-the-timeline check treated it as ending at 0 and dropped
it, so the clip froze on its first frame. Only an authored end (after the
start) at or before 0 now counts as before the timeline.

* fix(producer): only drop clips that start at or after the composition's end

A clip with no authored length carries end 0, the same value as an authored
end at 0, so "ends at or before 0" cannot be told apart from "natural
length" and a script-created clip with a negative start was dropped and
froze. Clips entirely before 0 keep main's behaviour; the filter now only
drops clips starting at or after the end, which never reads the end.

* test(producer): pin that a clip starting just before the end is still extracted
