🚨 Fix major hallucinations in SuperClaude documentation

CRITICAL FIXES:
- Remove all references to non-existent 'SuperClaude status' command
- Remove all references to non-existent 'SuperClaude diagnose' standalone command
- Remove all references to non-existent 'SuperClaude test-mcp' command
- Update diagnose references to use correct 'SuperClaude install --diagnose'
- Fix python help command references to use correct syntax

CONTEXT:
SuperClaude is a context-oriented framework with .md instruction files,
not an executable with extensive CLI commands. Only Python installer
supports: install, update, uninstall, backup operations.

VERIFIED COMMANDS:
✅ python3 -m SuperClaude --help (works)
✅ SuperClaude install --diagnose (works)
✅ SuperClaude install --list-components (works)
❌ SuperClaude status (does not exist)
❌ SuperClaude diagnose (does not exist)
❌ SuperClaude test-mcp (does not exist)

FILES FIXED:
- commands.md: status → config checks, diagnose → install --diagnose
- flags.md: status → config checks, help flags → help
- agents.md: diagnose → install --diagnose
- mcp-servers.md: status → config checks, test-mcp → /sc: commands
- modes.md: diagnose → install --diagnose
- session-management.md: status → list-components
