feat: add TypeScript, Vue.js and ESLint support with LSP, formatter and treesitter

- Add vtsls LSP with @vue/typescript-plugin for Vue hybrid mode
- Add vue_ls (Volar) for Vue 3 SFC support
- Add ESLint LSP for real-time linting
- Configure prettierd formatter for JS/TS/Vue/CSS/HTML/JSON via conform.nvim
- Add nvim-ts-autotag for auto-close/rename HTML and Vue tags
- Extend treesitter parsers: typescript, tsx, javascript, vue, css, json
- Add Mason ensure_installed for all new tools
