Strict mode warning when calling Flipper.add() on a new feature

[pelletencate]

When strict mode is enabled (:raise or true), calling Flipper.add("feature_name") immediately warns or raises "Could not find feature" before the feature is actually created.

Steps to reproduce

1. Set config.flipper.strict = true (or :raise)
2. In an IRB session, call Flipper.add(:bulk_gift_card_checkout)
3. Observe the warning: "Could not find feature... Call Flipper.add() to create it"

Expected behavior

Flipper.add() should create the feature without triggering strict mode warnings, since that's the method's purpose.

Actual behavior

Strict mode warning/error is raised before the feature is added to the database.

Environment

• Flipper version: 1.4.2
