Implement `snapcraft try` for core24 snaps, a known core24 migration gap. Triaged (Jira SNAPCRAFT-1185); a maintainer noted in July 2025 it's now implementable after Craft Application 5.0 refactoring, but the command still raises FeatureNotImplemented.

Suggested action: keep open

Reason: The issue is triaged (Status: Triaged, Type: Enhancement), acknowledged by maintainer @mr-cal who stated it is 'now possible to implement in Snapcraft' after Craft Application 5.0 refactoring, and tracked in Jira SNAPCRAFT-1185. The feature is still unimplemented at HEAD: TryCommand._run in snapcraft/commands/lifecycle.py unconditionally raises FeatureNotImplemented for all bases, and the core22-to-core24 migration guide still lists it as a known issue, so it remains relevant despite ~13.5 months of inactivity.

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.
