Support opening standalone `.flix` files without a workspace folder. LSP features (diagnostics, completions, hover, go-to-definition, etc.) now work in single-file mode. Changes: - Show warning notification on activation when in single-file mode - Use open text documents for file discovery instead of glob patterns - Replace filesystem watchers with document open/close listeners - Suppress "file not part of project" warning (no project boundary) - Set REPL cwd to the active file's directory in single-file mode Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
