Editor tooling

LukeLang runtime already provides protocol servers:

• luke LSP (hover, symbols, references, rename, formatting, semantic tokens, completion)
• luke DAP (debug adapter over gdb backend)

Official VS Code extension

Path: tools/vscode/lukelang/

Capabilities:

• .luke language registration + syntax highlighting
• snippets + keyword/type completion
• LSP client auto-starts vm/build/luke LSP (or lukelang.lukePath)
• DAP debug launches vm/build/luke DAP with launch configs

Settings:

• lukelang.lukePath — override binary path
• lukelang.enableLsp — toggle LSP
• lukelang.enableDebug — toggle debug adapter

bash scripts/vscode_extension_package.sh
