fix(formatter): disable automatic attribute collapsing by default

When the formatter automatically collapses attribute blocks, the
original content is lost and cannot be restored by the toggle
module. This broke the attribute expand/collapse functionality.

Changed default from collapseAttributes = true to false.

Users who want collapsing should:
1. Use :LspSCLFormat to format (preserves original content)
2. Then use :SCLCollapseAllAttrBlocks to collapse (stores original)
3. Now toggle/expand works correctly because content is stored
