amosblomqvist 6b58d87d9e electron+tests: zoom plumbing (construction-only lights), hermeticity fence for the jobs suite
- ZOOM: the ⌘±/⌘0 ladder is owned, not stock roles — applyZoom sets the
  factor and broadcasts 'lh:zoom'; the renderer publishes --lh-zoom; the
  gutter lengths (.lh-lights-gutter / .lh-closed-toggle) divide by it so
  their RENDERED size is a physical constant at every zoom — the graph
  button stays glued next to the lights, nothing slides under them.
  before-input-event catches ⌘=/layout variants the menu's Plus may not
  claim; did-finish-load re-pushes on reload; getZoom covers first paint.
  The lights themselves stay at construction position — Electron 44 has
  NO setTrafficLightPosition (options-only; the first run crashed on
  it). HIG-acceptable: native lights hug the corner; the web chrome
  compensates around them.
- JOBS SUITE FLAKE, actually fixed this time: the seams are
  module-global and the sweep scans every record — a timed-out async
  test left a running orphan + late wake that poisoned its NEIGHBORS
  (respawned 3 !== 0). New afterEach fence: settle every tracked
  running job, unregister aborts, seams reset to inert no-ops — every
  test starts from identical state regardless of upstream flake.
  Verified: two consecutive full-suite runs 1326/1326.

/*
* Preload (2026-09-17, narrow-window wave): the ONLY bridge between the
* sandboxed renderer and the main process. contextIsolation + sandbox are
* on (electron/main.cjs), so this file is the renderer's entire access to
* Electron — keep it a minimal, explicit API surface.
*
* window.lh.expandWindow() — widen the window to the sidebar auto-close
* threshold (928px) when the sidebar is opened below it. The main
* process clamps: no-op if the window is already wide enough.
*
* window.lh.onZoom(cb) / window.lh.getZoom() — the zoom truth (owner
* round 7, 2026-10-05): every ⌘±/⌘0 change arrives as "lh:zoom" with
* the new factor; getZoom covers the first-paint race. The renderer
* publishes it as --lh-zoom so physical-constant lengths (the traffic-
* light gutter) can divide by it.
*
* Channel names are mirrored in electron/main.cjs — keep them in sync.
