Inline strict SwiftLint and compiler flags in lint, build, and test tasks. Remove the STRICT configuration and forwarding from validation and CI, and update development documentation.
Replace the custom encrypted container with AgeSwift 0.1.0 so standard
age tools can inspect sensitive configuration independently of the app.
Use independent Keychain X25519 identities for catalog.age and
proxy-listening.age. Preserve atomic commits and confirmed recovery;
reject historical NG2 formats without migration or cleanup.
