Source locations were virtual, computed by recursing to the first and last
child, whose leftmost and rightmost leaves are token nodes; sequence-point
coordinates likewise came from reconstructed token nodes. Store locations as
fields assigned while printing, and derive sequence-point coordinates from the
surrounding real nodes plus the decompiler's fixed formatting, so neither
depends on token children. The using/foreach await modifier becomes a plain
bool field. Characterization gates lock the emitted locations and PDB
coordinates, which are unchanged.

The InsertMissingTokensDecorator path (TokenWriter.CreateWriterThatSetsLocationsInAST)
reconstructs token nodes and assigns source locations onto the AST, feeding PDB
sequence points and GUI navigation. The Pretty suite never drives it, so it had no
coverage at all. Before reworking the token model, lock its observable consequences:
the located path emits the same text as the plain path, real nodes receive ordered
locations, location-based navigation resolves into the method body, and sequence
points are produced for a method body.

The decompiled view only offered navigation on member names; finding
what an override actually overrides required opening the analyzer.
Attaching a reference to the modifier token gives the same
go-to-definition affordance Visual Studio has on 'override'. The
reference resolves via InheritanceHelper.GetBaseMember, so it targets
the nearest overridden member and degrades to plain text when the base
member cannot be resolved.
