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.

Tree-node selection now updates the inner Content of one persistent
ContentTabPage instead of swapping the dockable in the dock. The
wrapper view (ContentTabPageView) keeps both inner views — the
decompiler text editor and the metadata grid — pre-realised in the
visual tree from construction time and toggles which is visible based
on Content's runtime type.

Tree-node selections always operate on whatever document tab is
currently active. If the active tab is the wrong concrete type for the
new selection (e.g. a decompiler tab is up and the user picks a
metadata node, or vice-versa), the active dockable is replaced in
place — close the old, add the new, no sibling tab left behind.
Previously the host added a sibling tab and switched focus, which
piled up dockables and made "back to entity from metadata" feel
broken because the user could see two tabs competing for the slot.

Picking DOS Header → COFF Header → DOS Header was opening three
dockables because ShowCustomTab unconditionally added a fresh tab. The
docking host now searches for an open tab of the same concrete type,
copies the new node's tab state onto it, and re-activates it — same
shape as how the single decompiler tab gets reused across tree-node
selections.

DOS / COFF / Optional / DataDirectories / DebugDirectory now expose
their entries through CreateTab() instead of writing a fixed-width text
table from Decompile. The grid view shows each entry's columns
reflected directly off the row shape — Phase 1's text table was a
stand-in until this view shipped. The existing PE-header tests are
rewritten to assert against MetadataTablePageModel.Items / Columns;
adds a Waiters.WaitForMetadataTabAsync helper used by every grid-tab
test.

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.
