codegraph_explore's "Found N symbols across M files." header reported
`subgraph.nodes.size` / `fileGroups.size` — the raw FTS gather. A broad
natural-language query ("publish status to the API") matches a huge pool
(260 symbols / 124 files on a 636-file repo) while only a handful clear
the relevance gate + budget and render, so the header read as "260
results to wade through" even though the correctly-ranked answer was the
few files shown.
Report instead the files whose source actually SURVIVES in the final
output (after the hard-ceiling truncation that can drop trailing
sections), summing their relevant symbols. Gather, ranking, gate, budget,
and rendering are untouched — only the header string changes. Overflow
relevant files are still named under "Not shown above", so nothing is
hidden. Adds a regression test locking header-count == rendered-sections.
