Function compute_line_diff 

pub fn compute_line_diff(
    old_content: &[u8],
    new_content: &[u8],
    options: &DiffOptions,
) -> Result<Vec<DiffHunk>>

Compute line-level diff between two text contents

This function implements a simple line-based diff algorithm that:

1. Splits both texts into lines
2. Finds the longest common subsequence (LCS)
3. Generates hunks with context lines

Arguments

• old_content - Content from the source version
• new_content - Content from the target version
• options - Options controlling diff generation

Returns

Returns a vector of DiffHunk representing the changes
