Zeddotes Enhanced Code Block

Zeddotes Enhanced Code Block adds inspector controls to the WordPress core Code block:

• Language select with Prism.js highlighting in the editor and on the frontend
• Optional line numbers
• Tab key indents inside the block (Shift+Tab outdents); optional spaces instead of tabs
• Configurable tab size (2 / 4 / 8)
• Optional copy button before or after the code block, aligned left / center / right (or hidden)

No separate block type — authors keep using the standard Code block.
