Local Dev 53965db74d feat(addons): let an add-on talk to its own full-tab pages
api.emit() only ever reached the sidebar, even though addon-tab-preload has
always exposed silentmode.on() — so an add-on could hear from its panel but
had no way to tell its own editor tab anything. An add-on that wants a
second document to land in the editor already open, instead of a third tab
full of ribbon, needs exactly that.

Two small pieces:

- emitToPanel now also delivers to every tab owned by the same add-on. The
  sidebar keeps its existing condition; tabs are additional, not instead.
- addon-tab-focus, the counterpart of addon-tab-close: a page asking for its
  own tab to be fronted. Needed because the click that hands an open page
  something new usually happens somewhere else — the sidebar — and the
  result would otherwise appear in a tab nobody is looking at.

Both derive the tab from the sender's webContents, the way the close handler
already does, so a page can only front or close the tab it is itself in.

// Preload for full-tab pages opened by api.openTab("<file>", {query}) — the
// "open-tab" capability. Same window.silentmode surface as the sidebar
// preload (storage / invoke / on) but WITHOUT the sidebar's picker strip and
// resize grip, which have no place in a normal tab. Main derives the add-on
// identity from the sender's file:// URL, so a page hosted anywhere else
// gets nothing back from these handlers.
