Chisel integration test failing on ppc64el
Metadata
Current evaluation
Chisel integration test fails on ppc64el with an archive digest mismatch. CI is only green because the test carries a skipif for ppc64el referencing #1301; the underlying chisel/manifest problem is still unaddressed.
Suggested action: keep open
Reason: A maintainer-filed, labelled bug with an exact reproducer and full traceback; the log shows the root failure `error: cannot fetch from archive: expected digest fc67ac93..., got 7544888e...`, i.e. the chisel manifest digest for ca-certificates_data does not match what the ppc64el archive serves, which would also break real ppc64el builds that cut slices. The only mitigation in-tree is a skip (tests/integration/lifecycle/test_chisel_lifecycle.py: `platform.machine() == "ppc64el"` with reason linking #1301), which hides rather than fixes the failure, and the sibling test test_chisel_normalize_paths is still run on ppc64el. Zero comments in 381 days suggests upstream ownership (chisel/manifests) rather than a craft-parts defect, so it should stay open pending confirmation, not be closed as resolved or stale.

Issue body
### Bug Description
When running on `ppc64el`, `tests/integration/lifecycle/test_chisel_lifecycle.py::test_chisel_lifecycle` fails with an unspecified chisel error:
```
E craft_parts.packages.errors.ChiselError: Failed to cut requested chisel slices: ca-certificates_data
```
### To Reproduce
`pytest tests/integration/lifecycle/test_chisel_lifecycle.py::test_chisel_lifecycle` on a ppc64el machine
### part yaml
```shell
```
### Relevant log output
```shell

ec02157c 'fix(test): mark chisel integration tests as flaky' added `flaky(reruns=3, only_rerun="ChiselError")` retries (closing #1306); that mitigates transient network errors only and does not cover the deterministic ppc64el digest mismatch.

Commit 4193bd04 'ci: run non-plugin tests on more platforms' added ppc64el to the qa.yaml matrices and, together with it, the skipif on test_chisel_lifecycle that cites #1301 — the workaround came from the platform expansion, not a fix.
