Subject: [PATCH 02/11] fix: update macOS CI runner from macos-15 to macos-26
 for Swift 6.2 support

The J2KSwift dependency requires Swift 6.2 (swift-tools-version: 6.2.0),
which ships with Xcode 26. The macos-15 runner only provides Swift 6.1
via Xcode 16.x. Updated all workflows to use the macos-26 runner and
Xcode 26 selection.
