Stop long-running daemon operations from running under context.Background by\nthreading a request-scoped context from handleConn into dispatch. The daemon\nnow cancels in-flight handlers when the client socket goes away, and the RPC\nclient closes its Unix connection when the caller context is canceled so that\ninterrupts actually reach the daemon boundary.\n\nAdd regression coverage for both sides of the path: canceled dispatch calls,\nclient disconnects during handleConn, watcher EOF cancellation, and context\ncancellation without an RPC deadline.\n\nValidated with GOCACHE=/tmp/banger-gocache go test ./... and\nGOCACHE=/tmp/banger-gocache make build.
