fix(icons): drop the light rounded-square backing from the app icon (#2112)

* fix(icons): drop the light rounded-square backing from the app icon

The source SVGs drew an #EAE7E0 rounded rect behind the mark, which shows
as a pale border/frame around the icon on dark taskbars and in the app
window chrome. Remove the backing rect from both openidea.svg and
openidea-windows.svg, enlarge the mark to fill the canvas (scale 1.55 and
1.8 respectively), and regenerate the raster set with the tauri icon
toolchain.

Closes #2111

* fix(run): skip the drive prefix when canonicalizing verbatim roots

canonical_path walks a path component by component so it can compare a
not-yet-created base with existing sources. On Windows, a verbatim root
(\?\D:\...) puts a bare \?\D: Prefix component first; canonicalizing
that prefix alone fails with ERROR_INVALID_FUNCTION (GetFinalPathNameByHandle
has no directory form for a bare drive), aborting prepare() before any
work — the verbatim-roots test fails on windows-latest.

Skip Component::Prefix: the drive prefix has nothing to canonicalize, and
the RootDir right after it resolves the drive itself.

This fixes the same upstream-main failure tracked in #2057/#2096, scoped
to this branch so the icon change doesn't inherit a red job.
