`--reorder-code` inserts a blank line between a `##` doc comment and its declaration at the class-doc / first-member boundary

[minami110]

Tested on gdscript-formatter 0.21.0 (Pre-release 0.21.0-beta, published 2026-07-12), Linux x86_64. Upstream main checked up to 248fa13b (2026-07-12 09:20 UTC "Fix comments losing newlines between them in some cases") — that commit is related but in the opposite direction (comments losing newlines vs the bug here, comments gaining an unwanted newline). No fix found for this specific case.

Impact (style-guide deviation, non-breaking)

The GDScript style guide — Documentation Comments requires ## doc comments to sit directly above the declaration they document, with no blank line between. --reorder-code moves an existing blank line from between two ## blocks to between the second ## block and its declaration — losing the class-doc / member-doc boundary and turning the member doc into a free-floating comment.

Trigger

A file where the class-level ## doc block is separated from the first member's own ## doc comment by a blank line (i.e. the file is already correctly structured per the style guide).

Repro

Input (bug.gd):

class_name Foo
extends RefCounted
## file-level class doc block line 1
## file-level class doc block line 2

## member doc for MY_CONST directly above
const MY_CONST := 1

Command:

gdscript-formatter --stdout --reorder-code bug.gd

Actual output (--reorder-code)

class_name Foo
extends RefCounted
## file-level class doc block line 1
## file-level class doc block line 2
## member doc for MY_CONST directly above

const MY_CONST := 1

The blank line originally separating the class doc from the member doc has been moved to after the member doc, breaking the doc/declaration association.

Actual output (without --reorder-code)

class_name Foo
extends RefCounted
## file-level class doc block line 1
## file-level class doc block line 2

## member doc for MY_CONST directly above
const MY_CONST := 1

Plain formatting preserves the blank line's original position. The bug is specific to --reorder-code.

Expected

--reorder-code should leave the blank line where it was (between the class-doc block and the member-doc block), not relocate it to between the member-doc block and its declaration.
