spate-coordination 0.1.0

Distributed work coordination backend for the Spate pipeline framework: a leader-elected planner enumerates weighted splits into a shared low-latency store (NATS JetStream KV) and publishes a desired assignment per instance; workers lease and heartbeat what they are assigned, cooperatively drain what they are not, and commit progress through epoch-fenced compare-and-swap. Applications should depend on the `spate` facade crate with the `coordination` feature (in-memory store) or `coordination-nats` (the NATS backend).

# When uploading crates to the registry Cargo will automatically
# "normalize" Cargo.toml files for maximal compatibility
# with all versions of Cargo and also rewrite `path` dependencies
# to registry (e.g., crates.io) dependencies.
#
# If you are reading this file be aware that the original Cargo.toml
# will likely look very different (and much more reasonable).
# See Cargo.toml.orig for the original contents.
