Jonas Scholz ad4b882bff Fix e2b sbx logs -f <id> not following (#930)
This PR fixes 2 bugs that made the follow option in `e2b sbx logs` not
work:

1. `e2b sbx logs -f <id>` failed to follow because the `isRunning`
function was always returning false due to the API call being
unauthenticated if you dont have the `E2B_API_KEY` environment variable
set.

This follows the existing pattern from other API calls:

https://github.com/e2b-dev/E2B/blob/c4ce97e9b9a1809e3419d64499c1e56f9138e3d0/packages/cli/src/commands/sandbox/list.ts#L138-L152

Eventually it would make sense to handle the error here, for now just a
hotfix to fix the --follow usage

2. Once it actually followed, it never stopped following because
`isRunning` was not inside the loop and always true. Now when you kill
the sandbox follow actually stops following

> [!NOTE]
> Fixes `e2b sbx logs -f` by authenticating `isRunning` and re-checking
sandbox state each loop so following works and stops when closed.
> 
> - **CLI — `packages/cli/src/commands/sandbox`**:
>   - **Logs follow behavior (`logs.ts`)**:
> - Re-check `isRunning(sandboxID)` inside the loop (`isSandboxRunning`)
instead of using a cached promise, ensuring follow stops when sandbox is
closed or not found.
>   - **Sandbox state check auth (`utils.ts`)**:
> - Use `ensureAPIKey()` and pass `apiKey` to
`Sandbox.getInfo(getShortID(sandboxID), { apiKey })` so `isRunning` is
authenticated.
> - **Release**:
> - Changeset adds patch for `@e2b/cli` with note: fix sbx logs follow
option.

E2B CLI

This CLI tool allows you to build manager your running E2B sandbox and sandbox templates. Learn more in our documentation.

1. Install the CLI

Using Homebrew (on macOS)

brew install e2b

Using NPM

npm install -g @e2b/cli

2. Authenticate

e2b auth login

To authenticate without the ability to open the browser, provide E2B_ACCESS_TOKEN as an environment variable. You can find your token in Account Settings under the Team selector at e2b.dev/dashboard. Then use the CLI like this: E2B_ACCESS_TOKEN=sk_e2b_... e2b template build.

Important

Note the distinction between E2B_ACCESS_TOKEN and E2B_API_KEY.
