chore: remove unifiedStorageSearchSprinkles feature flag
The feature flag is no longer needed because:
- OSS: usageinsights code doesn't exist in OSS builds
- Enterprise On-Prem: uses local SQL storage when enable_search=true
- Cloud: explicitly configures sprinkles_api_server URL
The sprinkles functionality now works automatically based on:
- enable_search config (enforced true for unified storage mode 5)
- sprinkles_api_server config (empty = local storage, set = remote API)
* Transformers: Remove formatString feature toggle
The formatString feature toggle was in GA stage and enabled by default.
This change removes the feature toggle and makes the format string
transformer always available.
Changes:
- Remove formatString feature toggle definition from registry
- Remove conditional check in standardTransformers.ts
- Update feature toggle git log with deletion timestamp
- Regenerate feature toggle files
* fix lint errors
Remove regressionTransformation feature toggle
The regression analysis transformation feature is now GA and no longer needs to be behind a feature toggle.
