`namespace Foo {}` parses as `internal_module` and `module Bar {}` (and
ambient `declare module "pkg" {}`) as a named `module` node. Neither kind
was in `class_types`/`function_types` nor handled by an extra-walk, so the
container produced no node — its members were still reached by the default
recurse, but the namespace/module itself was invisible to the graph and its
members lost their namespace context.
Add `_ts_extra_walk`, dispatched for TypeScript after `_js_extra_walk`,
mirroring `_csharp_extra_walk`: it emits a container node + a file→container
`contains` edge and recurses the body, leaving members file-contained as
before. `internal_module` exposes `name`/`body` fields; `module` exposes
none, so name (identifier / nested_identifier / quote-stripped string) and
body (`statement_block`) are found positionally. The `is_named` guard skips
the anonymous `module` keyword token, which shares the `module` type string.
