remote-build does not exit with error upon partially successful builds
Metadata
Current evaluation
remote-build returns exit code 0 even when some architecture builds fail/stop; the unconditional `return 0` at the end of `_monitor_and_complete` in commands/remote.py is identified as the cause. Unlabelled, no maintainer response yet.
Suggested action: needs triage
Reason: The defect is verified in current code: `_monitor_and_complete` in craft_application/commands/remote.py classifies arches into succeeded/not_building sets but ends with an unconditional `return 0`, while the attached log shows 'Stopped: ppc64el, riscv64, s390x; Succeeded: amd64, arm64, armhf' followed by a success exit. However, the issue has no labels, no assignee and zero comments, so it has never been assessed by a maintainer. Impact is moderate (remote-build is flagged 'experimental', but a false-success exit code silently breaks CI and can lead to publishing incomplete rocks); complexity is low-to-moderate because the fix is a few lines plus unit tests, though the 'Stopped' state mixes genuine failures with post-upload completion, which needs a design decision. Actionability is high: an exact permalink to the offending line plus step-by-step reproduction and full logs.

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.
