Local LLM server on the 6800 XT (ollama-rocm, gfx1030 needs no
HSA_OVERRIDE_GFX_VERSION) fronted by a LibreChat web UI, talking to it
over the OpenAI-compatible /v1 route. Also wires up LibreChat's
persistent-memory feature, which needed its own agent+model plus a
custom extraction prompt: the default 3b model couldn't reliably tell
the user's stated facts apart from its own boilerplate, and even a
tuned prompt didn't fix that — so memory extraction now reuses
gemma4:12b, the same model as the daily-driver chat endpoint.
flake.lock bump pulls in the ollama and librechat NixOS modules.
