Done the way the owner asked and the spike mapped: the crate and the manifests renamed, then what the build reported fixed. Layers: 138 "proto unresolved" errors across 169 files; cargo fmt reordering imports; six fixture paths built as strings in brokerd's and bxctl's tests, which the compiler cannot see, and comments naming crates/proto/; the crate-dependency check and its self-test. One more the spike did not reach: a `\nproto =` key inside a printf format in the self-test, which a word-boundary replacement skips because `n` and `p` are both word characters. make gate: gate: ok, 944 tests; no new entry in /tmp.
