remote-build does not exit with error upon partially successful builds
Metadata
Current evaluation
remote-build exits 0 even when some architectures fail on Launchpad, because _monitor_and_complete unconditionally returns 0. Unlabeled, no maintainer response, 227 days old; bug still present in current code.
Suggested action: needs triage
Reason: The issue is a genuine bug with a clear root cause (unconditional `return 0` at remote.py:237) and reproduction steps, but it has no labels, no assignee, and zero maintainer comments in 227 days, so it has never been triaged. The bug is still present in current code (verified: `_monitor_and_complete` returns 0 unconditionally), so it should not be closed as stale or not-a-bug. A related snapcraft issue (#4783) was fixed for a different failure mode (missing artifacts), but this partial-failure exit-code case remains unfixed.

Issue body
### Bug Description
When building a rock that supports multiple architectures with `rockcraft remote-build`, the run exits with 0 return code even if the build is only partially successful (i.e., the builds of some architectures failed early without exceeding the time limit).
The cause is the `return 0` [in the code](https://github.com/canonical/craft-application/blob/5e0eda6ad7606c35008f104bc13e039bdd16bb74/craft_application/commands/remote.py#L237).
We should return a non-zero exit code if not all the architectures are successfully built.
### To Reproduce
Use any `rockcraft.yaml` file that has more than one architecture defined in `platforms`, e.g.
```
platforms:
amd64:
arm64:
armhf:
ppc64el:
riscv64:
s390x:
```
When the build runs in launchpad, cancel one or more builds in the LP project.
