This extension ports the main ideas of hlchunk.nvim to VS Code:
indent guides for visible lines
optional blank indentation fill
current chunk highlighting based on indentation around the cursor
gutter and line range highlighting for the current chunk
The VS Code API does not expose Neovim-style virtual text overlays or line-number highlight groups directly, so this implementation uses editor decorations and gutter markers. Chunk detection is indentation-based and does not require Tree-sitter.
