v0.1.1 — workspace housekeeping Changed: - `rtb-core` renamed to `rtb-app`. The primary export is the `App` context; the old name was abstract and invited mis-reading. Every `use rtb_core::…` must be updated to `use rtb_app::…`; every Cargo dep renamed from `rtb-core` to `rtb-app`. No API signatures changed. - `rtb-credentials::Resolver` now clones `SecretString` directly on the literal-credential path instead of round-tripping through a plain `String`, keeping the value inside the zeroize-on-drop container for the whole copy. See CHANGELOG.md § [0.1.1] for migration notes.
