Function traverse_from_memories 

pub fn traverse_from_memories(
    conn: &Connection,
    seed_memory_ids: &[i64],
    namespace: &str,
    min_weight: f64,
    max_hops: u32,
) -> Result<Vec<i64>, AppError>

Traverses the entity graph by BFS from seed memories.

Returns memory_ids reachable through entity and relationship edges, excluding the seeds themselves. The algorithm:

1. Collects entities associated with seeds via memory_entities.
2. Runs BFS over relationships filtered by weight >= min_weight and namespace.
3. Returns memories linked to discovered entities (excluding soft-deleted).

Errors

Propaga AppError::Database (exit 10) em falhas de consulta SQLite.
