Registers all 37 editor themes at startup via ThemeRegistry.bootstrap.js.
Side-effect module: requiring it populates the registry from a static
THEMES array (25 existing menu themes refactored into the registry +
12 new: Catppuccin x4, one-light, tokyo-night-storm, synthwave-84,
outrun, winter-is-coming x2, solarized-dark-hc, spring-light).
Categories split: 13 light / 22 dark / 1 high-contrast / 1 seasonal
(spring-light per spec).
Snapshot test asserts exact id order, shape validity, and category
counts. Tests use jest.resetModules() + per-test requires so the
bootstrap module re-evaluates its registration loop each run.
