AI assistant of @schickling feat: set process.title so pty processes are identifiable in ps/top/htop (#48) 12d ago

feat: set process.title so pty processes are identifiable in ps/top/htop (#48) Under Node 24+, V8 names the main thread "MainThread", so every pty process (the bin/pty signal-forwarding wrapper, the CLI, each session daemon, and the supervisor) shows up as `MainThread` in ps/top/htop/btm. That makes them indistinguishable from any other Node process and hurts observability and leak triage. Set `process.title` early in each entry point so they report a meaningful name instead: - bin/pty -> "pty" (signal-forwarding wrapper) - src/cli.ts -> "pty" (CLI) - src/server.ts -> "pty-daemon" (session daemon, guard-scoped) - src/supervisor-entry.ts-> "pty-supervisor" (supervisor) `process.title` is the only thing that overrides /proc/<pid>/comm, and only when set from within the running process after V8 init — launch flags (`node --title`, `exec -a`) do not work. Linux caps comm at 15 chars (TASK_COMM_LEN); all titles stay well under. Each assignment is wrapped in try/catch so it can never throw. server.ts only sets the title inside its `argv[1].endsWith("/server.js")` daemon-entry guard, since the module is also imported as a library (PtyServer). Adds a Linux-only test asserting a spawned daemon's /proc/<pid>/comm is "pty-daemon".
