Builds on Linux and macOS now connect to a shared `tsc-ts --api --listen` server by default, which keeps the files it parsed and bound, so a later build in the same working directory does not parse the TypeScript libs and scriptc's declaration files again. SCRIPTC_CHECKER_SERVER=0 turns it off. When CI is set to a value other than 0 or false, builds use their own tsc-ts process unless SCRIPTC_CHECKER_SERVER=1. - The server exits after 600 seconds without a build (was 300). - Its name also digests the compiler executable's identity, so each scriptc installation and build connects only to servers it started. - The server process runs in the root directory, so it does not keep the first build's directory in use; its --cwd argument is unchanged. - When the connection to the server fails after it answered, through a failed transfer or an ended stream, the native CLI runs the command again in a new process with SCRIPTC_CHECKER_SERVER=0 and exits with its status. - SCRIPTC_CHECKER_SERVER no longer changes the frontend cache key: the server's answers are the build's own checker's. The CLI docs describe the background process, its socket directory, when it exits and how to stop it.
