Delete the orphaned wiki/ dir (2nd copy of fabricated docs), dead top-level
tests/ (not compiled by the virtual workspace; stale signatures), excalidraw.log,
the fabricated GUI hero screenshot + unreferenced old-architecture SVGs
(c4_context, topology), stale RustRover run-configs for the moved GUI/TUI crates,
and committed Tauri-generated schemas under _reference/. Add .gitignore guards
(agent scratch, node_modules, dist, _reference gen) and align the local 'cargo
cov' alias to the de-gamed informational coverage (matches CI). Kept app_icon +
the nsql_pipeline/ipc_sequence SVGs still referenced by docs.
