Subject: [PATCH] fix: open more text file types in editor (nvim)

Expand textExtensions with many missing common text file extensions
(.lua, .rb, .vue, .svelte, .dart, .tex, .scala, .lisp, and many more).

Add textFilenames list for well-known text files without a meaningful
extension (Makefile, Dockerfile, README, LICENSE, .gitignore, etc.)
so they open in the editor via handleEdit() instead of falling back
to xdg-open via handleOpenExternal().
