fix(minimald): hide unplumbed --stdlib-dir and -n args from help - #846

Summary

minimald's GlobalArgs declares --stdlib-dir and -n/--num-parallel-builds, but neither is read anywhere in the daemon — the microVM path hardcodes both to None and the server Config consumes neither. --stdlib-dir was hidden only outside MINIMAL_SCIENCE_MODE, while -n was fully user-visible dead surface.

This hides both unconditionally with #[clap(hide = true)] so they no longer appear in help output. Since neither is plumbed even in science mode, there's no reason to surface them there. The flags still parse and are silently accepted, so any caller already passing them keeps working.

Change

     /// Load the minimal standard library from the given path instead
     #[arg(long)]
-    #[clap(hide = !std::env::var("MINIMAL_SCIENCE_MODE").is_ok())]
+    #[clap(hide = true)]
     stdlib_dir: Option<CwdRelative<Daemon>>,

     /// Configure the number of parallel builds
     #[arg(short, long, global = true)]
+    #[clap(hide = true)]
     num_parallel_builds: Option<usize>,

Testing

• cargo build -p minimald
• cargo clippy -p minimald --all-targets -- -D warnings
• cargo fmt -p minimald

Closes #825
