Round 1 + round 2 of adversarial review on the single-track timeline
(2092c8b) found and fixed:
- Clip position now stays absolute (seconds*pxPerSecond) instead of the
MIN_CLIP_PX floor cascading into every later clip -- a floored short
clip no longer pushes everything after it out of sync with the ruler.
- pendingSeek is cleared unconditionally right after project.select(),
closing a gap where a no-op select() (clicking within the already
selected clip) left it dangling for a later, unrelated draw to
wrongly replay.
- draw() now always resyncs the playhead to the current scene's start
on any non-track-click selection change, rather than only when the
old value fell outside the new scene's span -- the old check let a
stale playhead survive a wholesale project switch whenever it
coincidentally still fit the new project's first scene.
- The timeline moved from the centre column's own inner split to an
outer split above/below the whole three-column workspace, matching
v4's actual layout (full-width timeline under resizable columns,
not squeezed inside one of them).
- That restructuring put the Properties column under real height
pressure for the first time, exposing a latent bug: .cx-stack's
base rule set min-block-size:0 on every stack, letting a plain
grouping stack (not meant to scroll) get flex-crushed below its own
content height, so its overflow painted over the next row ("Settings"
over "Loosen the starting image"). Removed from the base rule --
.cx-stack-fill already carries it for the one case that should
actually give up height to scroll.
- Documented, rather than "fixed" by reintroducing the rejected
cascading-position bug: several under-floor clips in a row still
visually occlude each other (later DOM paints over earlier). Click-
seek still resolves correctly since it reads time, not paint order.
- Guarded framesOf() against a negative/NaN scene.length the same way
fps() already guards its own input.

Replaces the scene-index-tick ruler with composer's new track.default
element: clips sized by real duration (frames/fps, not equal-width
boxes), a ruler in genuine elapsed seconds, and a playhead that follows
the selected scene but can be dragged to any exact second within a
clip via click-to-seek.
Also fixes a real crash found while live-testing this: addScene()
built a scene object missing source_image/references, which crashed
the Inspector the moment it tried to draw the new scene.
