chore(deps): bump node-llama-cpp 3.18.1 → 3.20.0 and safe patch/minors (#891)

* chore(deps): bump node-llama-cpp 3.18.1 → 3.20.0 and safe patch/minors

Await LlamaContextSequence.dispose() before parent context dispose (3.20 made it async). flake.nix FOD hashes left stale on purpose.

* fix(nix): update qmd-node-modules FOD hashes after node-llama-cpp 3.20.0
