feat: add LogValue() method stub generation to MTLOG005 quick fixes

[willibrandon]

Description

Enhanced the MTLOG005 diagnostic to generate LogValue() method stubs for complex types, helping developers implement safe logging practices by automatically detecting and commenting out sensitive fields.

Type of change

• Bug fix
• New feature
• Performance improvement
• Documentation update

Checklist

• Tests pass (go test ./...)
• Linter passes (golangci-lint run)
• Benchmarks checked (if performance-related)
• Documentation updated (if needed)
• Zero-allocation promise maintained (if applicable)

Additional notes

• Generates idiomatic Go code with proper receiver names
• Works consistently in both VS Code and GoLand IDEs
• Includes test coverage for analyzer and GoLand plugin
• Helps prevent accidental logging of sensitive data
• Closes Add more quick fixes to VS Code and GoLand plugins #18 (completes all planned quick fixes)

Example generated code:

// LogValue provides a custom log representation for User
func (u User) LogValue() any {
    return map[string]any{
        "ID": u.ID,
        "Username": u.Username,
        // "Password": u.Password, // TODO: Review - potentially sensitive field
        // "APIKey": u.APIKey, // TODO: Review - potentially sensitive field
    }
}
