chore: reorganize into polyglot monorepo (workshop)

- Move bigmind/ -> mcp/bigmind/
- Move webscraper/ -> mcp/webscraper/
- Move mss-failsafe/ -> java/mss-failsafe/
- Move Wellmann-Shop/ -> java/wellmann-shop/ (normalize to kebab-case)
- Add .roo/ IDE config files to tracking
- Add plans/REPO_STRATEGY.md (monorepo strategy document)
- Expand .gitignore: Java/Maven, Node/TS, coverage, uv.lock
- Rewrite README.md as navigation index
- Update .roo/mcp.json webscraper path to mcp/webscraper/

+# Code Mode Behavior — Roo Code
+
+## Before Writing Code
+1. **Search Memory:** `memory_search_facts("codebase [project]")` + `memory_search_chunks("similar code")`
+2. **Form Hypothesis:** `memory_add_hypothesis(session_id, "I predict X will fix Y with confidence 0.8")`
+3. **Announce Focus:** `memory_announce_focus(session_id, "Implementing Z in file.py", files=["file.py"], ide_hint="VS Code")`
+
+## Coding Patterns
+- **Python:** Use uv for dependencies, FastMCP for MCP servers, pytest for tests
+- **Java:** Maven for Paisy projects, Spring Boot patterns
+- **Testing:** Always write tests first, mock external calls
+- **Token Efficiency:** Use `memory_log_token_save` when reusing code from memory
+
+## After Code Changes
+1. **Store Fact:** `memory_store_fact("codebase", "New function X in file.py does Y")`
+2. **Flag Important:** `memory_flag_important(session_id, "Code review: implemented Z", role="assistant")`
+3. **Resolve Hypothesis:** `memory_resolve_hypothesis(hypothesis_id, "confirmed", "Worked as predicted")`
+
+## Error Handling
+- If code fails, form new hypothesis: "Bug might be in dependency version"
+- Search: `memory_search_chunks("similar error")`
+- Debug systematically, log token savings from targeted searches
