Add Command-Line Support for Opening Local Builds

Overview

This change adds support for opening existing local .xml builds via command-line arguments.

Previously, Path of Building only supported opening builds through the pob2:// protocol, which is limited to importing builds from external sources. There was no way for external tools to open a build that already exists in the local builds folder.

Usage

PathOfBuilding.exe "<path>/Path of Building (PoE2)/Builds/MyBuild.xml"

Benefits

• Enables integration with external tools such as PoeLurker
• Enables desktop shortcuts to open specific builds directly

Compatibility

• Existing pob2:// protocol behavior is unchanged
• Launching without arguments behaves as before
• Invalid or missing files are handled gracefully (no crash)

Testing

• ✅ Launch with valid .xml filename → build opens correctly
• ✅ Launch with no arguments → default behavior unchanged
• ✅ Launch with pob2:// URI → protocol handler still works
• ✅ Launch with invalid .xml filename → no crash, fails gracefully

Do people really set up shortcuts for a single build on their computer? How is PoeLurker planning on implementing this?

I’d probably use shortcuts myself, but for PoeLurker I’m currently listing PoB builds and linking a build to a character in an overlay, and the only way to open the Skill Tree is via the official website URL embedded in the XML. It would be really convenient if users could open the build directly in PoB.
