feat: complete LSP and formatter configuration

- Add missing LSPs: lua_ls, bashls, yamlls, jsonls, marksman, taplo, sqls
  - Add missing formatters: prettier, shfmt, sqlfluff, cmake_format
  - Configure ruff with import organization and auto-fixes
  - Tune basedpyright to reduce diagnostic noise (basic mode)

  All LSPs verified attaching and formatters working correctly.
