openruntimes-executor crash loop after upgrading Appwrite 1.9.0 → 1.9.6 (container_name/hostname mismatch, undocumented)

### 💭 Description After upgrading Appwrite from 1.9.0 to 1.9.6, openruntimes-executor went into a permanent crash loop. Took a while to figure out why because the error message is useless: ``` Fatal error: Uncaught Utopia\DI\Exceptions\NotFoundException: Dependency response not found in .../di/src/DI/Container.php:74 ... Next Utopia\Http\Exception: Error handler had an error: Dependency response not found in .../Http/Http.php:534 ``` This loops forever and never says what actually failed. Turns out the real cause is in `app/http.php`'s `onStart` hook: ```php $hostname = gethostname(); $selfContainer = $orchestration->list(['name' => $hostname])[0] ?? throw new \RuntimeException('Own container not found'); ``` It looks itself up in Docker by matching `hostname` against the container `name`. Our compose had `container_name: openruntimes-executor` and `hostname: exc1`, different values, so the lookup fails and it throws. Checked appwrite/appwrite's own compose history: up to 1.9.0 they also had `container_name` different from `hostname`, and only made them match starting in 1.9.5. So this became a real requirement at some point but was never called out anywhere, not in the changelog, not in the upgrade notes for 1.9.5/1.9.6. If you're upgrading from an older install you just hit this with zero warning. On top of that, the reason we never saw the real error message: when the `onStart` hook throws, the framework tries to run the global error hooks, which need a `response` dependency that doesn't exist yet at startup time. That lookup fails too, and the *second* failure is all that gets logged. The original `Own container not found` never makes it to the logs. Two asks: 1. Document that `container_name` must match `hostname` for the executor, this is a breaking requirement for anyone upgrading from pre-1.9.5. 2. Fix the error handling so a failure during `onStart` actually gets logged before the error-hook machinery kicks in and (possibly) fails on its own. Reproduced on…
