### Bug Description When Launchpad's build queue is busy, the remote build tests will time out in CI. Things we should do in the fix: 1. Modify the init'd charm to only build on & for amd64 (so there's only one build in the queue where Launchpad typically has the most availability) 2. Extend the build time 3. Move the remote build tests to a scheduled weekly test rather than on every PR ### To Reproduce https://github.com/canonical/charmcraft/actions/runs/8096831733/job/22127019796?pr=1560 ### Environment CI ### charmcraft.yaml ```shell n/a ``` ### Relevant log output ```shell n/a ```
