When switching to a different project, the current configuration of the
previously active project is automatically captured into that project's
snapshot before the target project's snapshot is applied. Scope is limited
to the active group (Claude/Codex); autosave failures are collected as
warnings and do not block the switch.
- Move autosave logic into ProfileService::apply for consistent behavior
across UI, tray, and tests
- Add integration test covering bidirectional autosave roundtrip
