emozilla 43e67d872f feat: local models — managed llama.cpp runtime with one-click desktop setup
Run models locally as a first-class provider. The CLI grows a managed
llama.cpp runtime (engine install, model download, server supervision);
the desktop app grows the full setup and management story on top of it.
GUI surfaces ship behind the desktop --local launch flag (hermes desktop
--local, or the flag on the packaged app); backend routes and the CLI
are always live.

Runtime (hermes_cli/local_runtime/):
- curated GGUF catalog with per-machine variant selection: hardware
  probe (VRAM/RAM/UMA), fit planning with spill accounting, quant choice
  by context window
- derived recommendation: quality-ranked picks gated by a predicted
  decode-speed floor, bandwidth-aware on unified memory; the decision
  table is pinned as a test (pick AND reason per memory class), and the
  Recommended badge explains its pick in a tooltip fed by the resolver's
  actual branch
- engine install + model download with resumable split parts, cumulative
  plan-level progress, and staged-model integrity (a split GGUF counts
  only when every part is present)
- server supervision: spawn/adopt/stop, router mode with per-model load
  progress relayed over SSE, abandoned-request cleanup

Desktop:
- Settings -> Providers -> Local models: one-click quickstart (install
  engine, download the recommended model, boot) plus per-model download/
  activate/eject, fit-ranked catalog with context pills
- model pickers (composer dropdown + Cmd+K) show staged local models,
  in-flight downloads as live progress rows, and load-into-memory bars
- local-setup campaign tip for eligible hardware; System resources
  statusbar widget (GPU/VRAM/RAM); in-chat load progress during sends
- friendly dead-server errors, and failed agent builds retry on the next
  send instead of wedging the session

Co-developed with NVIDIA field feedback on RTX 5090 and DGX Spark.
