chore: bump core version to 10.1.0 (#946)

Updates centrally managed package versions to consume the stable `10.1.0` releases of the core Testably packages (moving off the prior RC), aligning dependency resolution across the repo (e.g., examples and helper projects that reference the NuGet packages).

fix: `Stopwatch` implementation on pre-release version 10.1.0-rc1 (#944)

This PR completes the release workflow for core library version 10.1.0-rc1 by updating package versions and restoring the build pipeline to build all projects (both core and main).

### Key Changes:
- Bumps core package versions from 10.0.0 to 10.1.0-rc1 in Directory.Packages.props
- Resets BuildScope from CoreOnly to Default to enable building all projects again
- Simplifies TestHelpers project references by removing unused Testably.Abstractions dependency

core/v10.1.0-rc1: feat: add `Stopwatch` support to `ITimeSystem` (#943)

2026-02-20T15:36:16Z

feat: add `Stopwatch` support to `ITimeSystem` (#943)

Adds a `System.Diagnostics.Stopwatch` abstraction to `ITimeSystem`, enabling both `RealTimeSystem` and `MockTimeSystem` consumers to create/use stopwatches through a testable interface.

### Key Changes:
- Introduces `IStopwatch` and `IStopwatchFactory` and wires them into `ITimeSystem`, `RealTimeSystem`, and `MockTimeSystem`.
- Implements real wrappers (`StopwatchFactory`/`StopwatchWrapper`) and mock implementations (`StopwatchFactoryMock`/`StopwatchMock`), plus parity and unit tests.
- Adds a feature flag for `Stopwatch.GetElapsedTime` (.NET 8 or higher)
- Adjusts build/project configuration (conditional PackageReference vs ProjectReference for the Interface project, pipeline + versioning tweaks).

feat: support async wait handlers (#942)

This pull request adds async wait handler support to the `IAwaitableCallback<TValue>` interface by introducing a new `WaitAsync` method. The changes enable asynchronous waiting for callbacks using modern async/await patterns with cancellation token support.

### Key Changes:
- Added `WaitAsync` method to `IAwaitableCallback<TValue>` for asynchronous waiting with cancellation support
- Refactored the interface to change the generic constraint from `out TValue` (covariant) to `TValue` (invariant) to support returning arrays
- Implemented channel-based async infrastructure using `System.Threading.Channels` for efficient value buffering
- Added comprehensive test coverage for the new WaitAsync functionality
- Updated API surface files across all target frameworks (.NET 6.0, 8.0, 9.0, 10.0, netstandard2.0, netstandard2.1)

v5.1.2: fix: fixed removing current directory not throwing ioexception (#940)

fix: fixed removing current directory not throwing ioexception (#940)

Aligns `MockFileSystem` behavior with Windows by preventing delete/move operations on the current working directory (or its parents) and throwing the same `IOException` patterns observed on the real file system.

### Key Changes:
- Added Windows-specific tests asserting `IOException` when deleting the current directory (and nested current directory) via both `Directory` and `DirectoryInfo`.
- Added Windows-specific tests asserting `IOException` when moving the current directory (and when the current directory is nested under the moved directory) via both `Directory` and `DirectoryInfo`.
- Implemented Windows-only “current directory handle” validations in `InMemoryStorage` and introduced new exception factory helpers.

fix: dot file entries not having hidden attribute on mac mock (#937)

Adds coverage and implementation changes to ensure dot-prefixed entries are treated as `Hidden` on macOS (and other non-Windows platforms) in the in-memory file system.

* fix: fixed dot file system entries not having hidden attribute when mocking mac

* test: moved Attributes_WhenDotFile_ShouldHaveHiddenFlag from FileVersionInfo to FileSystemInfo

* test: renamed InMemoryContainerTests.AdjustAttributes_LeadingDot_ShouldBeHiddenOnLinux to AdjustAttributes_LeadingDot_ShouldBeHiddenOnUnix and adjusted expectation

feat: add triggered notification handler for `IFileSystemWatcher` (#931)

This PR adds a new notification handler for `IFileSystemWatcher` that allows tests to be notified when file system changes are actually triggered by a watcher. This complements the existing `Notify` handler which fires on all file system changes.

### Key Changes:
- Introduces `IWatcherTriggeredHandler` interface with `OnTriggered` method
- Adds `Watcher` property to `MockFileSystem` exposing this handler
- Updates API test expectations across all target frameworks

refactor: fix or ignore sonar issues (#922)

This PR addresses SonarCloud issues by refactoring code to eliminate static analysis warnings. The changes focus on improving code quality without altering functionality.

### Key Changes:
- Removed redundant multiplication by zero in timer configurations
- Replaced `GetCustomAttribute<T>()` with more efficient `IsDefined()` calls
- Added pragma directives to suppress unavoidable SonarCloud warnings for complexity and parameter count

fix: set UnixFileMode when creating new mock file stream (#916)

This PR sets `UnixFileMode` when creating a new mock file stream via `MockFileSystem.FileStream.New(string, FileStreamOptions)`.

* Adds `UnixFileMode` argument to `FileStreamMock` constructors
* Sets `UnixFileMode` if valid `FileMode` is used
* Throws `ArgumentException` if invalid `FileMode` is used
* Passes `FileStreamOptions.UnixCreateMode` in `FileStreamFactoryMock` to `FileStreamMock`
* Adds new CallStatistics overload to handle an additional parameter
* Adds tests
