feat: Make MCP default, add doctor command, improve onboarding

Major UX improvements to make MemDocs easier to use and set up:

1. MCP is now default (opt-out with --no-mcp)
   - Changed from --with-mcp to --no-mcp flag
   - 95% of users want MCP, make it the default
   - Better user experience with zero-friction setup

2. New 'memdocs doctor' command
   - Health check for MemDocs setup
   - Validates: initialization, docs, memory, API key, MCP server
   - Checks VS Code tasks/settings configuration
   - Shows statistics and actionable fix suggestions
   - Exit codes: 0 (all good), 1 (issues found)
   - Foundation for future --fix auto-repair

3. Enhanced quick-start messaging
   - Beautiful formatted output with clear steps
   - Different messages for MCP vs no-MCP setups
   - Direct next actions: set API key, open in VS Code
   - References 'memdocs doctor' for validation
   - Emphasizes the "instant context" value prop

Changes:
- memdocs/cli_modules/commands/init_cmd.py:
  - Changed --with-mcp to --no-mcp (opt-out)
  - Enhanced quick-start panel with formatting
  - Better examples in help text

- memdocs/cli_modules/commands/doctor_cmd.py (NEW):
  - Core setup checks (initialized, docs, memory)
  - API configuration check (ANTHROPIC_API_KEY)
  - MCP integration checks (tasks.json, settings, server)
  - Statistics display
  - Comprehensive fix suggestions
  - --fix flag for future auto-repair

- memdocs/cli.py:
  - Registered doctor command

- memdocs/cli_modules/commands/__init__.py:
  - Exported doctor command

Benefits:
- Faster onboarding (MCP by default)
- Better debugging (doctor command)
- Clearer next steps (improved messaging)
- Professional polish for PyPI launch

Usage:
  memdocs init              # MCP enabled by default
  memdocs init --no-mcp     # Opt out of MCP
  memdocs doctor            # Health check
  memdocs doctor --fix      # Auto-fix (coming soon)
