Formatter behavior (quick summary)

• Indents func, if, else, and while blocks.
• Dedents on end_func, end_if, and end_while.
• return / return <value> are regular body statements and stay indented with the block they are in.
• exit / throw / error close active non-function blocks for following lines.
• Comment lines (# ...) are kept unindented.
• Single empty lines are preserved, runs of empty lines are collapsed to one, and leading/trailing blank lines are removed.
• A blank line is inserted before each block opener (func / if / while) that is not nested directly under another opener, and after each block closer (end_func / end_if / end_while), separating sibling blocks. else: stays attached to its if block.
