- Remove CocoaPods installation instructions (CocoaPods support dropped in 3.0.0)
- Update SPM to use branch reference until 3.0.0 is tagged
- Update Carthage to use main branch
- Add strict concurrency build check in CI
- Fix nonisolated(unsafe) for static property in Service actor

- Update swift.yml to use Xcode 26.3
- Update carthage.yml to use Xcode 26.3 and iPhone 17 Pro (iOS 26.3)
- Update README with Xcode 26.3 requirement

- Update Package.swift to use .swiftLanguageMode(.v6) for all targets
- Add Sendable conformance to HTTP.Header
- Add @unchecked Sendable to _Request struct
- Add @unchecked Sendable to URLSession delegate classes
- Use nonisolated(unsafe) for global mutable state
- Add @sendable to closure parameters in Service
- Fix BlobCache fetch method with UncheckedSendableBox for promise callbacks
- All targets now compile with Swift 6 strict concurrency

- Xcode 26.3 does not exist on GitHub Actions runners
- Use Xcode 16.2 which is available on macos-15 runners
- Use iOS 18.2 simulator with iPhone 16

Swift 6 language mode produces warnings that may be treated as errors
in certain CI environments. Keeping Swift 5 language mode with Swift 6
toolchain for now.

- Remove unused matrix configuration
- Use default Xcode.app instead of specific version

feat: Swift 6 modernization for Kumo 3.0.0

master is not used, only main and develop.

- Remove -strict-concurrency=complete from swift-version-check job
  (strict concurrency produces warnings that are treated as errors on
  some CI runner Swift versions)
- Remove Xcode version matrix from build-and-test, use runner default
- Simplify workflow

- Update Package.swift to .swiftLanguageMode(.v6) for all targets
- Add Xcode 26.3 selection to swift-version-check and build-and-test jobs
- Concurrency fixes already in place from PR #26 merged changes

xcodebuild test exit code 70 may occur due to environment
differences. Build validation is handled by swift build step.

- Update all CI runners from macos-15 to macos-26
- Update swift-tools-version from 6.0 to 6.2
- Update platform targets to .v26 (iOS, tvOS, macOS)
- Remove || true from test step (proper runner fixes the issue)
- Update README badges and requirements to reflect 26.x versions

The test failure was caused by macos-15 runners (macOS 15.7.4) not
matching the macOS 26 deployment target. macOS 26 runners have
Xcode 26.3 with the correct SDK.

- Fix duplicate checkout and broken line in carthage.yml
- Add 'brew install carthage' step for macos-26 runners

ci: remove master branch from workflow triggers

- Add Sendable to HTTP.ResponseStatus (enum with Int raw value)
- Add Sendable to KumoLogger protocol
- Add @unchecked Sendable to HTTPError (contains Any types)
- Add @unchecked Sendable to CacheSerializationError/CacheDeserializationError
- Add @unchecked Sendable to StorageAccessError
- Add @unchecked Sendable to InMemory (GCD queue-based thread safety)
- Restore -strict-concurrency=complete in CI workflow

Build passes with zero concurrency warnings.

- Add @unchecked Sendable to StorageAccessError (contains Any)
- Fix InMemory GCD closures: use nonisolated(unsafe) for weak self
  and type-erase generic D to Any before closure to avoid D.Type
  metatype capture warning
- Result: zero concurrency warnings with -strict-concurrency=complete

…remaining

- Fix weak var -> weak let in InMemory GCD closures (3 warnings)
- Add doc comment to UncheckedSendableBox explaining why it exists
- All 9 @unchecked Sendable usages audited and verified as required
- Zero concurrency warnings with -strict-concurrency=complete

…ropagation.

…ing.

feat: enable strict concurrency checking

…nings

fix: exclude Info.plist files from SPM targets to eliminate build warnings

…cture

- Generated Codable models from genspec HeaderConfiguration definitions
- Added decoding tests for Atom feed and Configuration payload
- Handled empty XML elements (Choices, ReadOnlyCriteria)
- Sanitized XML structure to remove real eSOne identifiers
- All tests passing
