v0.2.3 - ???????

Highlights

• Adds an eleven-lesson beginner learning path from installation to a first map.
• Introduces Addon, Hammer, Lua, KV, Modifier, Panorama, static checks, debugging, and Git in a fixed order.
• Separates beginner learning from the formal human verification checklist.
• Routes learners to focused handbook chapters after the first development loop.

Workshop Tools runtime validation is still pending, so this remains a prerelease.
