### Added

- **The .NET timing caution now reaches applications that carry the runtime inside the
executable.** An application published as NativeAOT or as a self-contained single file has no
.NET runtime files beside it, and those files were how the session recognised .NET, so it never
got the caution that a `Stopwatch` timer does not follow the session speed. The session now also
looks for the marker the .NET runtime leaves inside the executable itself. Two builds carry no
such marker and are still not recognised: a framework-dependent single file, and a NativeAOT
application published with debugger support turned off.
- **The .NET timing caution now reaches .NET applications that leave no runtime files beside

.NET Framework application, whose runtime lives in the Windows directory, and one started as
`dotnet app.dll` have no .NET runtime files beside the executable. Those files were how the
session recognised .NET, so none of these got the caution that a `Stopwatch` timer does not follow

Correct the prior-coverage claim.

The previous export-based detector already warned for NativeAOT and self-contained single-file applications with matching runtime exports. “None of these got the caution” incorrectly presents that coverage as new. Describe framework-dependent single-file apps, .NET Framework executables, and dotnet app.dll as the newly recognized cases.

As per path instructions, “Check that documentation matches the actual code in this PR.” As per coding guidelines, flag changelog “entries that do not match what the PR actually changes.”

In `@CHANGELOG.md` around lines 12 - 16, Revise the changelog coverage claim to
distinguish newly recognized cases from existing export-based detection:
identify framework-dependent single-file apps, .NET Framework executables, and
`dotnet app.dll` as newly covered, and do not imply NativeAOT or self-contained
single-file apps lacked the warning when matching runtime exports were present.

the runtime's own exports, the signature every .NET launcher carries, and the header of a .NET
Framework program - and recognises the `dotnet` host by name. One build carries none of them and
is still not recognised: a NativeAOT application published with debugger support turned off.
- **A caution when the application was built with Go.** The Go runtime reads the date straight
from shared system memory rather than asking Windows for it, so a Go application sees the real
date and nothing this tool can do will change that. The session time zone does reach it, which
