Fix move view subscribers

[kelindar]

This PR fixes the issue of Resize() view, when in certain scenarios the subscribers weren't properly updated (either subscribe or unsubscribe). Also Rect API has changed, it is now exclusive of the bottom-right boundary to align with more widely adopted approaches.

View Enhancements:

• Enhanced View functionality by adding a MoveTo method and refining the Resize method to handle view changes more efficiently in view.go.
• Updated view_test.go to include new test cases for MoveTo and adjusted existing tests to reflect changes in View behavior. [1] [2] [3]

Rect Enhancements:

• Improved Rect API by modifying Contains, Intersects, and Size methods to be value receivers and added new methods like IsZero and Difference for better rectangle operations in point.go.
• Refactored Within and WithinRect methods of Point to utilize the new Rect methods.

Dependency Updates:

• Updated Go version to 1.23 and upgraded dependencies github.com/kelindar/iostream to v1.4.0 and github.com/stretchr/testify to v1.9.0 in go.mod.
