context-forge 0.7.0

//! Integration test for Phase 3 secret scrubbing: proves that a secret
//! present in `save`-d content never reaches the on-disk database (entries
//! table or FTS index), and that the opt-out path stores it verbatim.
//!
//! Previously this test used a raw rusqlite connection to bypass the library.
//! With the turso backend the on-disk file contains a `USING fts` index that
//! is incompatible with rusqlite's schema parser, so we now verify via
//! ContextForge's storage APIs, which read the raw stored content directly
//! (no read-time scrubbing is applied).
