Simplify neural and goal module initialization

## Summary
Simplified the `neural init` and `goal init` commands to create only essential agent files, removing unnecessary config.json and README.md generation.

## Changes Made
- ✅ Removed config.json generation from neural init command
- ✅ Removed README.md generation from neural init command
- ✅ Removed config.json generation from goal init command
- ✅ Removed README.md generation from goal init command
- ✅ Updated wiki documentation with new AI Modules section
- ✅ Updated Neural Module docs to remove config/readme references
- ✅ Updated Goal Module docs to remove config/readme references

## Benefits
- Cleaner initialization with less file clutter
- Configuration is built into agent definitions themselves
- Simpler user experience
- Faster module setup

## Version
Released as v2.0.0-alpha.110

## Testing
Both commands tested and verified to create only the agent markdown files:
- `.claude/agents/neural/safla-neural.md`
- `.claude/agents/goal/goal-planner.md`

Start by running the `neural init` and `goal init` commands and checking whether they produce only `.claude/agents/neural/safla-neural.md` and `.claude/agents/goal/goal-planner.md`. Compare the current wiki AI Modules, Neural Module, and Goal Module documentation with the stated behavior; done means no config or README files are generated and those references are removed.
