chore: prune unused apps and services for the moeka fork

- Remove stage-tamagotchi, stage-pocket, server, and engine workspaces with their workflows, addons, and docs
- Switch the toolchain from pnpm to bun, replace lockfiles with bun.lock

-> The `dev` and `start` scripts run `install-electron` before `electron-vite`.
->
-> Electron 42 removed the `postinstall` script. The `electron` package now downloads its binary
-> when you first run its `bin` entry. `electron-vite` reads `node_modules/electron/path.txt`
-> directly, so it never starts that download. A fresh install therefore fails with
-> `Error: Electron uninstall`.
->
-> `install-electron` runs the same code as the removed `postinstall` script. It returns
-> immediately when the binary is already present.
->
-> Remove this step after `electron-vite` supports the lazy download.
