Nearly every headless UI test opened with the same four-line prologue
(resolve the shared MainWindow, show it, cast its DataContext, wait for the
assembly list), then repeated the corelib lookup, the EnsureLazyChildren +
Children.OfType<T>().Single() drill, the registry single-by-header lookups,
and the open-an-assembly-and-wait dance. The duplication made the intent of
each test hard to see and every signature tweak a suite-wide edit.
Collapse those into TestHarness (BootAsync, OpenAssemblyAsync, GetCommand,
GetEntry) and TreeNavigation extensions (FindCoreLib, GetChild<T>, Expand<T>),
then apply them across the suite. Net ~865 lines of boilerplate removed with
no change in behaviour; the full headless suite stays green.
Replace the single text-bar above the grid with one filter input per
column, baked into each DataGridColumn's header. The page model carries
a ColumnFilters collection alongside Columns; the filter predicate ANDs
every non-empty column's case-insensitive substring match. Column
instances are built fresh per page so sibling tabs don't share filter
state, and the column name moves to Tag for cell-level lookups now that
Header is a Panel.

The grid view's row-virtualisation handles the full heap (CoreLib's
truncation-footer wording are gone. Existing heap tests are rewritten
to assert against MetadataTablePageModel; the obsolete
MetadataHeapTreeNode.PreviewLimit constant follows the cap into the
deleted set.

Adds the four CLI heap views (#Strings, #US, #GUID, #Blob) under each
assembly's Metadata folder. Phase 1 caps each heap's text dump at 200
preview rows with a truncation footer; the full set arrives with the
DataGrid view in Phase 2. Heap rows are materialised lazily on first
demand so opening the Metadata folder doesn't pay for heaps the user
never visits.

Adds the five PE-format leaves (DOS / COFF / Optional / DataDirectories
/ DebugDirectory) under each assembly's Metadata folder. Phase 1 renders
them as fixed-width text tables via Decompile; Phase 2 will swap to a
DataGrid tab. Introduces Entry / BitEntry / ColumnInfoAttribute and a
MetadataTextWriter helper that the heap and table nodes reuse.
