Implement Feature Request: Allow Comment Alignment At Different Columns #1

[skkdevcraft]

This PR improves ASM comment alignment behavior by allowing independent comment alignment blocks instead of forcing all consecutive comments into a single shared column.

It also fixes tab-width handling by using the editor formatting configuration (tabSize, insertSpaces) instead of hardcoded tab assumptions.

Example:

# global comment
# global comment 2

                      # this comment starts with #
	mov     bx, %eax  # aa
                      # bb

                    ; this comment starts with ;
	mov     ax, bx  ; comment
                    ; comment 2
                    ; comment 3

Changes included:

• support multiple independent comment alignment regions
• preserve intentional manual alignment styles
• fix continuation comment alignment
• use VS Code formatting options for visual width calculation
• remove hardcoded tab-size assumptions

This improves readability and produces more consistent formatting across different editor configurations.
