Two test fixtures carried their own copy of the 32-byte signature, which
would silently drift from the real one. The signature is now an internal
member of SingleFileBundle and ILSpy.Tests gets internals access to the
decompiler assembly, matching what ILSpyX already grants it.

Backfills the standard MIT X11 header on hand-written files that never
got one, attributing each to its first-commit author and year from git
history. Code vendored from dotnet/runtime and Humanizr/Humanizer gets
its origin's license lines and a provenance note instead. Generated
files (Resources.Designer.cs, the version-info template), tool-managed
suppression files, and BAML test-case fixtures intentionally stay
header-less.
