feat(codexlens): add staged settings for advanced configuration and update related components

- Added new staged settings in config.py for coarse_k, lsp_depth, stage2_mode, and clustering strategy.
- Updated config-handlers.ts to handle new staged settings and map environment variables.
- Enhanced codexlens.json localization files for English and Chinese to include new staged settings.
- Modified astgrep_js_ts_processor.py to improve import handling for named imports.
- Updated JavaScript and TypeScript patterns to support new import formats.
- Added tests for staged settings loading and performance benchmarks for stage-2 expansion.
