Move summaries to tmp/summaries with cache and combine support

- Output summaries to tmp/summaries/ instead of alongside source files
- Add per-module timestamp caching (skip up-to-date modules)
- Add combine_summaries() to merge all into all_summaries.md
- Extract LLM provider and model to config variables
- Reorganize script: config, discovery, utilities, worker, main loop

 Keep summaries concise but do not oversimplify complex algorithms - include enough detail
 to understand the logic and approach. Focus on public interfaces, not internal implementation details.
