Finds the registered project carrying the huskies source tree, runs `cargo build --release` inside its container (dedicated CARGO_TARGET_DIR=target/sled-release so container builds stop clobbering host target/release), then atomically publishes the binary to ~/.huskies/artifacts/ with a .hash sidecar for convergence checks. Full fleet redeploy is now chat-only: `release` then `upgrade all` — no laptop access needed.
