0.22.0

• Based on roc-lang/basic-cli 0.21.0-rc4 for the new Roc compiler.
• Add spawned child processes with piped stdio:
  • Cmd.spawn! / Cmd.spawn_grouped! return a Cmd.Child with piped stdio.
    Grouped children die with the parent (PR_SET_PDEATHSIG on Linux, managed
    process groups elsewhere) and can be culled with Cmd.kill_grouped!, which
    also runs automatically on program exit.
  • Child.write_stdin!, Child.read_stdout!/read_stderr! (blocking exactly-N
    reads, as length-prefixed protocols need), close_stdin!, wait!, poll!,
    kill!. stdout/stderr are drained into buffers by background threads from
    spawn time, so a chatty child never deadlocks on a full OS pipe buffer.
• Add Tcp connection pooling:
  • Tcp.pool! creates a host-managed pool. max_connections caps total
    connections (checked out + idle). At the cap, pool_acquire! waits for a
    release (30s timeout -> TcpConnectErr(TimedOut)).
  • Streams are pool-aware: a checked-out stream that is dropped without
    pool_release! frees its slot, so leaks cannot wedge the pool.
    Tcp.close! shuts a socket down immediately for connections in an
    unknown protocol state.
