`snapcraft try` for `core24`
Metadata
Current evaluation
Core24 `snapcraft try` support remains unimplemented; current code explicitly raises FeatureNotImplemented. Maintainers confirmed it is now feasible after Craft Application 5.0 refactoring.
Suggested action: keep open
Reason: The current TryCommand still raises FeatureNotImplemented for core24 and core26, its unit and spread tests assert that failure, and the migration guide lists the limitation. Maintainer @mr-cal explicitly called the feature valuable, said it is now implementable after Craft Application 5.0 refactoring, and linked it to SNAPCRAFT-1185.

Issue body
### What needs to get done
Please implement `snapcraft try` for `core24`-based snaps. This is a known issue noted in the migration guide to core24.
### Why it needs to get done
`snap try` is a valuable tool for development in our Ubuntu Core-based system, it shortens the time between tweaking the code and seeing a result. Our current workaround to use it is to unpack the snap after it was built, but this wastes time on the initial build of a project and complicates our build scripts.
