Add useany linter: Detect interface{} and suggest replacing with any

🚀 New Features

New Linter: useany

Added a new golangci-lint plugin that detects interface{} usage and suggests replacing it with any (Go 1.18+).

Key Features:

• 🔍 Detects interface{} in all contexts (variables, functions, structs, etc.)
• 🛠️ Full auto-fix support with golangci-lint --fix
• 🎯 Only targets empty interfaces, won't flag interfaces with methods

Example:

// Before
var data interface{}

// After (with --fix)  
var data any

Installation:

1. Add to .custom-gcl.yml:

plugins:
  - module: 'github.com/qor5/linter'
    import: 'github.com/qor5/linter/useany'

2. Enable in .golangci.yml:

linters:
  enable:
    - useany
