The current native quantizer marks Q4_1 unsupported. The original implementation likely just needs to be restored before upstreaming. | Contributor Author | You rock!

Integrate the CLI, agent, server, download targets, and conversion tools. Preserve the native Q4_1 encoder, Q4_K accumulation guard, and shared quantizer build target. Keep exact-MTP rewind and vision-cache row-width fixes. Persist valid logits and recurrent state at completed prefill chunks, and reuse Qwen text-answer history when tools clients omit reasoning. Retain exact reasoning replay and test continued checkpoints, cancellation, cache eviction, and restart reuse with and without reasoning_content. Include reproducible charts and measurements comparing throughput before and after the checkpoint fixes on M3 Ultra. Add Qwen trunk steering and prompt activation capture, including GDN layers. Keep the MTP predictor outside the 48-row bank and preserve prompt dumps through one-token prefill tails and multi-row speculative verification. Recover Chrome target creation and retain its last page target. Preserve full agent transcripts in stripped-session format when KV no longer fits, while retaining the newer automatic compaction and continuation logic. Add steering/MTP/capture, Chrome CDP recovery, and full-session save/reload regressions. Adapt the intended changes from fork PRs #13 and #7. Reconcile with antirez main bd66c40, preserving DeepSeek v4.1 model IDs, tool syntax, session state, and Metal kernel dispatch. Exclude superseded engine code and prototypes.
