# Enhance init experience with robust GitHub integration and interactive defaults

## Summary

This PR significantly improves the `mem8 init` command user experience by making it interactive by default, implementing robust GitHub CLI integration, and making helper commands more forgiving. The changes focus on streamlining the initialization flow and resolving issues with GitHub account detection.

## Changes

### 🎯 Key Improvements

1. **Robust GitHub CLI Integration** (commit 2f4a3b0)
   - Replace fragile string parsing with structured JSON-based GitHub CLI interface
   - Add `GitHubContext` class with multiple detection strategies (API, JSON, fallback)
   - Implement `GitHubCommand` builder pattern for consistent command execution
   - Improve handling of multiple GitHub accounts with active account detection
   - Make interface resilient to GitHub CLI format changes
   - Resolves inconsistent account detection between multiple authenticated accounts

2. **Interactive-by-Default Init Flow** (commit 4bf9897)
   - Change `--interactive` flag to `--non-interactive` (interactive is now default)
   - Reorder flow to ask workflow provider first for GitHub-centric experience
   - Remove unimplemented Linear option, focus on GitHub vs none
   - Use active GitHub account as default instead of saved preferences
   - New flow: Workflow Provider → GitHub Config → Template → Username → Automation
   - Improved messaging for local repos not yet pushed to GitHub

3. **More Forgiving Metadata Command** (commit f87aafd)
   - Make `topic` argument optional in `mem8 metadata research` (defaults to "research")
   - Improve research_codebase.md template with clearer examples
   - Add template management documentation to CLAUDE.md
   - Reduces errors when Claude Code agents call commands

4. **Updated Test Suite** (commit d516978)
   - Update tests for interactive-by-default behavior
   - Fix test input sequences for new workflow provider-first flow
   - Add `--non-interactive` flags where tests expect automated behavior
   - All key tests pass with new flow structure

### 📝 Files Changed

- `mem8/integrations/github.py` - New robust GitHub CLI interface
- `mem8/cli_typer.py` - Interactive default, reordered init flow, optional metadata topic
- `mem8/core/utils.py` - Enhanced GitHub detection
- `mem8/templates/.../research_codebase.md` - Clearer command examples
- `CLAUDE.md` - Template management documentation
- `tests/test_init_*.py` - Updated for new flow

## Migration Notes

### For Users

- `mem8 init` is now interactive by default - use `--non-interactive` for old behavior
- GitHub repository detection improved - better handling of multiple accounts
- When using GitHub workflow provider, you'll be prompted to configure it early in the flow

### For Developers

- Tests that relied on `--interactive` flag should now use `--non-interactive` instead
- GitHub CLI commands now return structured JSON instead of parsed text
- Template changes in `mem8/templates/` apply to new projects via `mem8 init`

## Testing

- [x] All existing tests updated and passing
- [x] Interactive init flow tested manually
- [x] GitHub detection tested with multiple accounts
- [x] `mem8 metadata research` works with and without topic argument
- [x] Template regeneration works via `mem8 init --force`

## Breaking Changes

None - the changes are additive or improve existing behavior. Users who relied on non-interactive mode by default will need to add the `--non-interactive` flag.

## Changelog Entry

```
