BrightScript tree-sitter:

1. Clone the existing grammar:
   git clone https://github.com/ajdelcimmuto/tree-sitter-brightscript

2. Build the grammar:
   cd tree-sitter-brightscript
   npm install
   tree-sitter generate

3. Add to Helix languages.toml:
   [[language]]
   name = "brightscript"
   scope = "source.brightscript"
   injection-regex = "brightscript"
   file-types = ["brs", "bs"]
   comment-tokens = ["'", "rem"]
   indent = { tab-width = 4, unit = " " }
   language-servers = ["brighterscript-lsp"]

[[grammar]]
name = "brightscript"
source = { path = "/path/to/tree-sitter-brightscript" }

4. Build grammar for Helix:
   hx --grammar fetch
   hx --grammar build
