Rewrite research workflow to lead with literature mining

Research sub-agent now starts from papers, not docs. Default workflow:
anchor paper → citation graph crawl → read methodology sections →
extract result-attributed recipes → validate datasets → then code.

Output format requires ranked recipe table linking results to the
exact dataset + method + hyperparams that produced them.

+## The crawl
 
-# Research methodology
+1. **Find anchor papers**: Search for the task/domain. Identify the landmark paper(s) — high citations, recent, or both.
+2. **Crawl the citation graph**: Use `citation_graph` on the anchor paper(s). Look DOWNSTREAM (papers that cite it) — these are the ones that built on it, improved it, or applied it to new domains. Prioritize recent papers and papers with many citations.
+3. **Read methodology sections**: For the most promising papers (strong results, recent, relevant), use `read_paper` with section parameter to read sections 3, 4, 5 (Methodology, Experiments, Results — not the abstract). Extract:
+   - The exact dataset(s) used (name, source, size, any filtering/preprocessing)
+   - The training method and configuration (optimizer, lr, schedule, epochs, batch size)
+   - The results those choices produced (benchmark scores, metrics, comparisons)
+4. **Attribute results to recipes**: This is the critical step. Every finding must link a RESULT to the RECIPE that produced it. "Dataset X + method Y + lr Z → score W on benchmark V" is useful. "They used SFT" is not.
+5. **Validate datasets**: For the most promising datasets, check if they exist on HF Hub with `hf_inspect_dataset`. Verify format matches the training method. Report if doesnt.
+6. **Find code**: Now find working implementation code via `github_find_examples` and `github_read_file`. Use docs (`explore_hf_docs`, `fetch_hf_docs`) to fill in API details.
 
-1. **Discovery**: Find relevant entry points — example scripts, doc pages, API endpoints, **and recent papers for SOTA approaches**
-2. **Tracing**: Follow the chain from entry point to implementation detail
-3. **Analysis**: Identify patterns, current API usage, key dependencies. **Compare against SOTA from recent papers**
-4. **Synthesis**: Summarize findings in a structured format, highlighting what is current best practice vs. outdated

+- If a downstream paper reports significantly better results, crawl ITS citation graph too.
+- Use `snippet_search` to find specific claims across papers (e.g., "does dataset X consistently outperform Y for this task?").
+- Use `recommend` to find related papers the citation graph might miss.

+## Code patterns
+- Key imports, configurations, and usage patterns from working examples
+- Specific file paths, URLs, function names from docs
+
+## Recommendations
+- Which recipe to implement first and why
+- What datasets to use (with HF Hub paths, verified)
+- Any gaps: datasets that need preprocessing, methods that need adaptation
+
+Additionally include:
 - **SOTA landscape**: Current best models, datasets, and methods for the task (from recent papers). Flag anything outdated.
-- **Key findings**: The most important things you discovered (current API usage, working patterns)
 - **Essential references**: Specific file paths, URLs, function names, doc sections, code snippets
   that the main agent should use directly
 - **Code patterns**: Key imports, configurations, and usage patterns from working examples
-- **Recommendations**: What to do next based on your findings, preferring SOTA approaches
