Current evaluation

Adds conditional strict platform-name validation via craft-platforms, exempting legacy Ubuntu 20.04–24.04 bases; remains open with failing fast, minimum-dependency, and lint checks plus one unresolved thread.

Suggested action: keep open

Reason: Four checks are failing, and the fast test validates '/' while asserting an error about '.', leaving an unresolved review thread. Although there has been no activity for 210 days, main still lacks the craft-platforms validator integration, so the change is not demonstrably superseded and should remain open pending fixes.

Issue body

This implements strict platform name validation using the validator in craft-platforms (see: https://github.com/canonical/craft-platforms/pull/209) By default, projects only get validated if their base doesn't match any of our "legacy" bases (ubuntu 20.04-24.04). - [x] Have you followed the guidelines for contributing? - [x] Have you signed the [CLA](http://www.ubuntu.com/legal/contributors/)? - [x] Have you successfully run `make lint && make test`? - [x] Have you added an entry to the changelog (`docs/reference/changelog.rst`)? ---
