Summary of imported compatibility changes
--------------------------------------------------------------------------
Added Node-RED 5.x editor compatibility, without breaking Node-RED 4.x
support (single file works on either version). In short, NR5 moved the
tab bar out of #red-ui-workspace into a new #red-ui-header container
that also hosts the logo and Deploy button, which this plugin's
original DOM/CSS assumptions did not account for. The imported changes:
  - Detect NR4 vs NR5 tab bar location at mount time
  - Correct positioning context for the injected two-row tab bar on NR5
  - Header height now grows to fit the two-row bar without breaking
    the Palette/Workspace/Sidebar layout below it, measured at runtime
    rather than hardcoded
  - Avoid a CSS custom-property self-reference cycle that could cause
    runaway layout sizing
  - Prevent the injected tab bar from visually covering the Deploy
    button / hamburger menu
  - Prevent the flows-row's background from bleeding onto the canvas
    when a group has few flows
