Add setMinSize() and setMaxSize() methods

[zhuxiaojt]

@twlite

Adds setMinSize and setMaxSize APIs to control window size constraints, aligned with the logical parameter pattern from #38. Pass (0, 0) to clear the constraint.

@zhuxiaojt could you fix the merge conflict?

[Lawtro37]

If you change

dpi::{LogicalPosition, LogicalSize, PhysicalSize, Size},

to

dpi::{LogicalPosition, PhysicalPosition, LogicalSize, PhysicalSize, Size},

that should fix the merge conflict.

I noticed that these features have already been implemented in commit cf8cc47. Should I close this PR, or is there any further work needed on my side?

Commit diff snippet for cf8cc47:

+  /// Set minimum inner size.  Pass `null` / `undefined` for both to remove the
+  /// constraint.
+  #[napi]
+  pub fn set_min_size(&self, width: Option<f64>, height: Option<f64>) {
+    let size: Option<winit::dpi::Size> = match (width, height) {
+      (Some(w), Some(h)) => Some(LogicalSize::new(w, h).into()),
+      _ => None,
+    };
+    self.window.set_min_inner_size(size);
+  }

+  /// Set maximum inner size.  Pass `null` / `undefined` for both to remove the

I think this can be closed
