Run the server.cpp directly inside the Go runtime via cgo
while retaining the LLM Go abstractions.

* remove c code
* pack llama.cpp
* use request context for llama_cpp
* let llama_cpp decide the number of threads to use
* stop llama runner when app stops
* remove sample count and duration metrics
* use go generate to get libraries
* tmp dir for running llm

- read runner options from map to see what was specified explicitly and overwrite zero values
