Add build.py script for incremental compilation
Adds a build-only script that syncs src/ into an existing Vitis
workspace and rebuilds the app without recreating the platform/BSP.
Faster than re-running checkout.py for iterative src/ edits.

Usage: vitis -s <path-to-scripts-repo>/build.py
3
+
Builds an existing Vitis workspace without recreating the platform.
4
+
Syncs source files from src/ into the workspace, then compiles.
5
+
6
+
Requires a workspace already created by checkout.py.
7
+
Much faster than checkout.py for iterative src/ edits since it skips
8
+
platform/BSP rebuild.
