fix: update command aliases for consistency and clarity

[dermatz]

Remove short command codes, keep descriptive aliases only

Summary

Removed short command codes (e.g., m:t:b, m:s:c) from all CLI commands. These are unnecessary since bin/magento and magerun2 provide auto-completion. Only descriptive aliases are now used.

Changes

Removed short codes:

• m:t:b → removed (use frontend:build)
• m:t:c → removed (use frontend:clean)
• m:t:l → removed (use frontend:list)
• m:t:w → removed (use frontend:watch)
• m:s:c → removed (use system:check)
• m:s:v → removed (use system:version)
• m:h:t → removed (use hyva:tokens)
• m:h:c:c → removed (use hyva:check)

Current aliases structure:

• Theme commands: frontend:* (build, clean, list, watch)
• System commands: system:* (check, version)
• Hyvä commands: hyva:* (tokens, check)

Updated files

• All command classes in src/Console/Command/
• README.md (root) - Updated examples
• src/README.md - Updated command table

Why

Short codes are redundant - Magento CLI and magerun2 already provide command auto-completion. Descriptive aliases improve readability and are easier to remember.
