fix(cli): add electron as runtime dependency for fusion desktop

The published @runfusion/fusion package ships the desktop runtime assets
in dist/desktop/, but the [title-id-drift] db.ts migration normalized 0 active titles
[done-paused-backfill] db.ts migration repaired 0 done task rows
[title-id-drift] archive-db normalized 0 archived titles

} command calls require('electron')
to find the Electron binary. Electron was only declared as a built
dependency in pnpm-workspace.yaml, which makes it available during source
builds but does not include it in the published npm package. As a result,

} fails or hangs for npm consumers.

Fix: move electron to the dependencies of @runfusion/fusion so it is
installed alongside the CLI, and remove it from onlyBuiltDependencies.

Fixes: the desktop launcher regression where [title-id-drift] archive-db normalized 0 archived titles

+summary: Add `electron` as a runtime dependency so `fusion desktop` works from a published npm install.
+category: fix
+dev: `packages/cli/package.json` now depends on `electron`. Previously the desktop launcher called `require("electron")`, which is only available inside the source checkout (via `pnpm-workspace.yaml` `onlyBuiltDependencies`) and is missing for npm consumers, causing `fusion desktop` to hang or fail silently.
