v0.7.2

[0.7.2]

Added

• Added semantic_mode (lexical, semantic, or hybrid) and optional query_embedding support to both synchronous and asynchronous recall clients.
• Added optional embedding and event_time support to both memory-write clients, plus one-vector-per-produced-chunk embeddings for raw-content ingestion.
• Added synchronous and asynchronous classify_intent() helpers for the engine's query/memory intent API.
• Added directory preview, persisted include-path updates, and watch-scope reads to both clients.
• Updated release documentation for the qint8 MiniLM-L3 default and q4 MiniLM-L3 edge profile.

Removed

• Removed the old embedding-free client description; semantic retrieval is now an explicit, local engine capability rather than an experimental client-side feature.
• Removed CuePack parameters because CuePacks are no longer part of the v0.7.2 Rust API.
