Add Pocketenv CLI
Add a new CLI app under apps/cli with commands (login, whoami,
start, stop, create, ssh), an axios client and envalid config, plus
package.json and bun.lock.
Implement login flow that opens the browser and persists the token
to ~/.pocketenv/token.json.
Also remove an unused import in env.ts, enable express.json in the
bsky router, and add a 'cli' query param to the projects route.
