Establishes the governance floor for Cerebra v0.1: six Lattica primitives vendored, inspector event infrastructure, constitutional and leeway loaders, SQLite migration framework, and a working `cerebra init` command with full inspector event emission.
Fixed tauri dev CWD detection in get_project_root to pop src-tauri directory and return true project root, resolving absolute paths without the extra segment.
Added runtime path resolution (Rust get_project_root + TS builder) to convert manifest's portable relative paths to absolute editor URLs, plus error visibility and editor picker UI.
Fixed useState+useEffect race in HistoryTab by deriving overrides via useSyncExternalStore, matching the override system's reactivity pattern.
