AbstractCore v2.13.23

Added

• Generic capability plugin contract: added the planned Core/plugin contract record for optional modality plugins, including shared provider/model discovery, typed task methods, host text-generation access, and cycle-free plugin integration expectations.
• Music capability integration: added first-class music output routing through llm.generate(..., output="music"), the llm.music.generate(...) facade, and typed server routes for POST /v1/audio/music and POST /{provider}/v1/audio/music when abstractmusic is installed.
• Memory bloc maintenance control plane: added public local helpers and matching server operations to list, delete, and prune blocs or provider/model KV artifacts while preserving live-binding safety checks for loaded cache keys.

Changed

• Capability registry consistency: normalized voice, audio, vision, and music plugin discovery around a shared Core-owned registry surface so optional plugins can expose capabilities without hard dependencies or import cycles.
• Server media routing: music requests now support request-level backend/model/provider routing and typed music parameters instead of relying only on environment-selected plugin defaults.
• Documentation set: refreshed README, API, server, capabilities, memory-bloc, backlog, and LLM index docs for the new music and bloc-maintenance surfaces.

Verified

• Music smoke proofs: generated valid 3-second WAV outputs through both Python generate(..., output="music") and the server music route using the local AbstractMusic ACE-Step backend.
