feat(lua): expand LuaLSP, Treesitter and pack helper configurations

Why: improve language support and fix a client API typo

- New Features
  - Added extensive filetype list for Tailwind LSP (astro, blade, ejs, etc.) and enabled the language server
  - Extended Treesitter parser list with regex, latex, tsx, svelte, typst, vue
  - Introduced PackChanged autocmd that notifies on install/update builds
- Enhancements
  - Disabled unused provider loaders (node, perl, python3, ruby)
  - Registered additional filetype handlers for various template extensions
  - Updated markdown style setting and filledchars option
- Bug Fixes
  - Corrected client:supports_method call in autocmd.lua (removed stray colon)
