LLMFlux v2.0.0

This is a major release and contains breaking changes — see CHANGELOG.md for the full list with rationale.

The headline feature is multi-node vLLM inference (#137, #141): --nodes N now shards a model across all N nodes instead of starting a server on the first and leaving the rest idle, using vLLM's own rendezvous under a single SPMD srun step — no Ray, no container change. See docs/MULTINODE.md.

Breaking changes

• Config.__init__ gained workspace as its first positional parameter, shifting the directory arguments. Pass them as keyword arguments.
• Batch and serve jobs now exit with the processor's / server's status instead of always 0.
• Five public Config members were removed, along with SlurmConfig.mem and the unprefixed DATA_INPUT_DIR / DATA_OUTPUT_DIR environment variables.
• llmflux connect now validates the node and port it reads from connection.json, and a directory passed to --input now raises.

The CLI surface is unchanged — same subcommands and flags as v1.0.0 — so for command-line users this bump is about behaviour, not interface.

Notable fixes

• llmflux run works again where the container directory is admin-owned and read-only (#138).
• llmflux benchmark no longer downloads its dataset into the installed package (#146).
• llmflux serve --engine ollama now exits with the server's status and publishes one resolved endpoint host, matching the vLLM path.
