`redundant_self` false positive with Logger

New Issue Checklist

• I've Updated SwiftLint to the latest version.
• I've searched for existing GitHub issues.

Bug Description

Sample Code

import os

class Name {
    private let test = ""

    func testLog() {
        Logger(subsystem: "sub", category: "cat").warning("test: \(self.test, privacy: .private(mask: .hash))")
    }
}

SwiftLint output:

$ swiftlint    
Linting Swift files in current working directory
Linting 'a.swift' (1/1)
~/Desktop/a.swift:7:68: warning: Redundant Self Violation: Explicit use of 'self' is not required (redundant_self)
Done linting! Found 1 violation, 0 serious in 1 file.

When removing the self. from the self.test:

$ swift a.swift
a.swift:7:68: error: reference to property 'test' in closure requires explicit use of 'self' to make capture semantics explicit

   |                                                                    `- note: reference 'self.' explicitly
 8 |     }

Environment

• SwiftLint version (run swiftlint version to be sure): 0.63.2
• Xcode version (run xcodebuild -version to be sure): Xcode 26.3 Build version 17C529
• Installation method used (Homebrew, CocoaPods, building from source, etc): Homebrew
• Configuration file:

opt_in_rules:
  - redundant_self

redundant_self:
  only_in_closures: false

Start by reproducing the SwiftLint 0.63.2 report with the sample code and the shown redundant_self configuration. Trace the redundant_self rule's handling of the Logger interpolation and compare it with Swift's requirement for explicit self in the closure. Done means the required self.test is no longer reported as redundant while other redundant_self violations remain covered.
