7a9d01342a Fix inconsistent Vegas scroll transition gaps caused by plugin-baked padding (#384)
* Strip plugin-baked scroll padding when capturing content for Vegas mode

Plugins that build their own ticker image via ScrollHelper.create_scrolling_image()
(or that manually pad both ends for a clean standalone loop) carry a solid-black
margin up to display_width wide on one or both edges. Vegas mode already adds its
own configurable gap around every item, so leaving that margin in place stacked an
extra, uncontrolled blank stretch on top of separator_width for whichever plugin
took the ScrollHelper-capture path — producing inconsistent transition gaps between
modules compared to plugins that provide content natively via get_vegas_content().

_get_scroll_helper_content() now detects and crops any such margin before handing
the image to the Vegas render pipeline, so every plugin's gap is governed solely by
vegas_scroll.separator_width regardless of which capture path produced its content.

* Address CodeRabbit nitpick: warn on double-edge padding crop, add unit tests

Logging a double-edge match at warning level (vs. info for a single edge)
makes it easy to spot an unexpected crop in the field, since two edges
matching at once is a much stronger signal of genuine baked-in padding than
one edge coinciding with real all-black content.

Also adds test/test_vegas_plugin_adapter.py covering _strip_scroll_padding's
branch logic: leading-only, trailing-only, both-edges, no-match, degenerate
all-black, missing/undersized display_width, and the info-vs-warning log level.

* Add type hints and docstring to test _solid helper (CodeRabbit nitpick)
