Run one test and audit the repo without retyping either (V-653)

Two commands replace work that 66 sessions of transcripts show being
redone by hand.

`make t` replaces the CGO preamble, pasted 391 times across past
sessions and documented in CLAUDE.md as the way to do it. It also sets
MAVEN_ONNX_LIB, which that recipe did not: the four TestONNX*
measurements self-skip without it and the run still prints "ok", so
every targeted eval done the old way reported the hash ratchet while
reading as a real embedder score. -race keeps it honest against `make
test`, -count=1 keeps a stale cache from passing as a result.

`make audit` replaces the inventory sweep. The four longest sessions
spent 93 greps rebuilding it before their first edit. Runs in 0.75s.

Its stub search is narrower than the sweeps were, on purpose. "not
wired" is this repo's word for a nil dependency and matched ~30
comments describing working code; "placeholder" names real identifiers
and matched 16 more; internal/ipc/unimplemented.go is the deliberate
Unimplemented*Server pattern, not 60 gaps. A gap report that reports
the architecture back at you is one nobody reads twice.

-Run a single test (must carry the CGO env for packages that touch STT/TTS/voice):
+Run one package or one test with `make t`. **Do not hand-write the CGO preamble.**
+Past sessions pasted it about 390 times. That is where the shell-quoting failures
+came from. This box runs zsh, so an unquoted `-run Test*` or `--include=*.go`
+dies on "no matches found" before `go` is ever reached.

-Pure-Go packages (`router`, `memory`, `mavweb`, …) run under a plain `go test ./pkg/`.
+`t` carries `-race`, so a green `make t` cannot turn red under `make test`. It carries
+`-count=1`, so a cached PASS from before your edit is never mistaken for a result.
+
+It also sets `MAVEN_ONNX_LIB`, which the hand-written recipe did not. The four
+`TestONNX*` measurements self-skip when that variable is unset. The run still prints
+`ok`. So every targeted eval done the old way reported the hash ratchet while reading
+as a real embedder score.

+Pure-Go packages (`router`, `memory`, `mavweb`, …) also run under a plain `go test ./pkg/`,
+but `make t` works everywhere and is one thing to remember.
