Current evaluation

Maintainer-filed enhancement to add the disable-parallel part property to the uv plugin; explicitly low priority pending a real-world use case and a design decision on Python plugins (#1247).

Suggested action: keep open

Reason: Valid, maintainer-authored parity enhancement (lengau) that is triaged with labels 'Type: Enhancement, Status: Needs information' and an explicit maintainer comment, so it should stay open. However, no implementation is possible yet: the body says it is 'extremely low priority until someone shows us a real-world use case', and lengau's comment ('We need to figure out what we're doing for Python in general in #1247 before we decide how that applies to uv') shows it is blocked on the Python plugin design. Code inspection confirms the uv plugin never uses parallel_build_count (only autotools, cmake, make, go, colcon, bazel, qmake do), so 'disable-parallel' has no existing parallel path to disable, and the Autotools precedent (craft_parts/plugins/autotools_plugin.py:49,133 — 'make' vs 'make -j{N}') is a different plugin family.

Issue body

### What needs to get done Support the [disable-parallel](https://canonical-craft-parts.readthedocs-hosted.com/latest/common/craft-parts/reference/part_properties/#disable-parallel) part property in the uv plugin. ### Why it needs to get done All of our plugins should theoretically support this. In practice though, this is extremely low priority until someone shows us a real-world use case for it. If someone can bring us a real-world use case that we can test against (especially a case of "this application simply does not build with parallel"), that would be ideal. The [autotools plugin](https://github.com/canonical/craft-parts/pull/1167) required this for OpenJDK builds, for example.

    Maintainer comment explicitly defers the uv design until the python plugin's approach (3-state None/True/False) is decided.

  • Related To: craft-parts#1232 (confidence 70%)

    Same low-priority disable-parallel parity series for other plugins (ant, make, go, java, maven, npm, rust); only autotools is implemented so far, per changelog line 522.
