Authenticate the E2B SDK and CLI with an API key (and migrate off access tokens)

Documented steps
Create an API key in the dashboard (https://e2b.dev/dashboard?tab=keys); each key is scoped to exactly one project (https://e2b.dev/docs/api-key)
Export it as E2B_API_KEY for SDKs and CLI alike; SDKs also accept it explicitly, e.g. `Sandbox.create({ apiKey: '...' })`
For CI/headless use, setting E2B_API_KEY is sufficient — `e2b auth login` (browser flow) is only needed for interactive use and requires CLI >= 2.12.1 for API-key auth (https://e2b.dev/docs/migration/access-token-deprecation)
Raw REST calls (e.g. lifecycle events API at api.e2b.app) authenticate with the `X-API-Key` header
Known gotchas
E2B_ACCESS_TOKEN is deprecated: new tokens cannot be generated after 2026-07-01 and ALL access tokens stop working on 2026-08-01 — any request still using one will fail; switch to E2B_API_KEY now
Keys are per-project (projects replaced 'teams'): templates, sandboxes, billing and concurrency limits all follow the project the key belongs to (https://e2b.dev/docs/projects)
