feat: Add unified Typer CLI and Dev Container setup

## Unified CLI (cli_unified.py)
- Single `empathy` command with nested subcommands
- Uses Typer + Rich for beautiful CLI output
- Delegates to existing CLIs for robust compatibility
- Command structure:
  - empathy memory (status, start, stop, stats, patterns)
  - empathy provider (config, registry, costs, telemetry)
  - empathy scan/inspect (code analysis)
  - empathy morning/ship/health/fix-all (workflows)
  - empathy wizard/workflow (domain wizards)
- Includes cheatsheet command for quick reference

## Dev Container (.devcontainer/)
- One-click dev environment with VS Code
- Python 3.11 + Redis 7 pre-configured
- Extensions: Python, Ruff, Black, MyPy, Pylance
- Auto-installs dependencies on container create
- Redis available at redis://redis:6379
