Full rename of the project/scheme/target/source folders and identifiers via scripts/apply-rebrand.sh. Bundle id thewonderofyou.Feather → app.ftstore, display name → FTStore, developer → FTStuff, website → ftstore.app. CoreData model, bridging header and entitlements renamed in lockstep; upstream signing team cleared. Rewrites app-repo.json, README, Makefile and CI workflows. Image assets, the all-caps FEATHER_* build vars, LICENSE and upstream attribution/credits are intentionally preserved; project stays GPL-3.0.
