feat: tighten preset filter, tame storage load logs, enable rollout prompt by default (#3628)

Summary
- common: use exact equality for Swiftfox exclusion to avoid hiding
future slugs that merely contain the substring
- core: treat missing internal_storage.json as expected (debug), warn
only on real IO/parse errors
- tui: drop DEBUG_HIGH gate; always consider showing rollout prompt, but
suppress under ApiKey auth mode
