Persist profiles before install; save even if installs fail

[pablopunk]

Summary

• Persist user-specified active profiles to state before starting installation, ensuring dot <profile> is saved even if installs fail or the run exits early
• Add regression test verifying profiles are saved when an install command fails (e.g., sh: false)

Why

• Users expect their selected profiles to be remembered immediately; previously profiles were saved late in the run. If anything aborted before saving, the selection could be lost.

Details

• In App.Run, when profiles are provided by the user and not in dry-run, we persist them to the state file prior to installation
• Kept existing post-install saves for consistency; the pre-save is additive and safe
• New unit test: TestProfileSavedEvenIfInstallFails

Test plan

• go test ./... passes
• Unit test explicitly checks that the state’s ActiveProfiles includes the chosen profile even if a component install fails
