- build.rs: drop the stale `rerun-if-changed=src/client.rs` (the file
became client/ in W7; the path never fires).
- lib.rs: the crate doc's module list named 6 of ~19 modules — add the
missing ones (config/error/stats/input/reject/reanchor/render_scale/
audio/wol + the quic-gated control-plane group), without intra-doc
links to feature-gated modules.
- quic/mod.rs: the module doc still described the deleted `msgs`
module; list the actual post-split module set.
