feat: Timmy fixes and improvements (#72)

* test: remove hardcoded sleeps, add pytest-timeout

- Replace fixed time.sleep() calls with intelligent polling or WebDriverWait
- Add pytest-timeout dependency and --timeout=30 to prevent hangs
- Fixes test flakiness and improves test suite speed

* feat: add Aider AI tool to Forge's toolkit

- Add Aider tool that calls local Ollama (qwen2.5:14b) for AI coding assist
- Register tool in Forge's code toolkit
- Add functional tests for the Aider tool

* config: add opencode.json with local Ollama provider for sovereign AI

* feat: Timmy fixes and improvements

## Bug Fixes
- Fix read_file path resolution: add ~ expansion, proper relative path handling
- Add repo_root to config.py with auto-detection from .git location
- Fix hardcoded llama3.2 - now dynamic from settings.ollama_model

## Timmy's Requests
- Add communication protocol to AGENTS.md (read context first, explain changes)
- Create DECISIONS.md for architectural decision documentation
- Add reasoning guidance to system prompts (step-by-step, state uncertainty)
- Update tests to reflect correct model name (llama3.1:8b-instruct)

## Testing
- All 177 dashboard tests pass
- All 32 prompt/tool tests pass

+## Communication Protocol
+
+**Before making changes, always:**
+1. Read CLAUDE.md and AGENTS.md fully
+2. Explore the relevant src/ modules to understand existing patterns
+3. Explain what you're changing and **why** in plain English
+4. Provide decision rationale - don't just make changes, explain the reasoning
+
+**For Timmy's growth goals:**
+- Improve reasoning in complex/uncertain situations: think step-by-step, consider alternatives
+- When uncertain, state uncertainty explicitly rather than guessing
+- Document major decisions in DECISIONS.md
+

 ## Non-Negotiable Rules
 
 1. **Tests must stay green.** Run `make test` before committing.
