fix(qwen): un-exempt opencode, and keep the Qwen key in a secret
Two findings this round contradicted each other — one asked me to extend the
engine-spec exemption to a bare "opencode", the other said opencode should not
be exempt at all. The code settles it: that engine drives an ollama-cloud model
through the bundled CLI and authenticates with OLLAMA_API_KEY, so it needs
exactly the key the pre-flight checks. Exempting it, which I did last round,
switched the check off for the one engine it could still help. Only claude-code
is exempt now — it carries CLAUDE_CODE_OAUTH_TOKEN and needs no Ollama key —
and opencode/open-code get table rows so both spellings are covered.

The README told operators to embed the Qwen key in a GADFLY_ENDPOINT_* var,
while the workflow that forwards those vars warns in its own comments that vars
are NOT masked. Rather than only rewording the docs, a keyless kimi/qwen
endpoint now falls back to its own QWEN_API_KEY / KIMI_API_KEY — the same
vendor's key, so the no-cross-vendor rule is untouched — which lets the URL live
in a var and the credential in a secret. Break-checked by pointing that fallback
at OPENAI_API_KEY: the leak test catches it.

Smaller: isBuiltinCompatProvider mirrors isOpenAICompatProvider instead of an
inline slices.Contains, with a test that every builtin is also in the compat
list (a builtin missing from it would never reach the branch that protects it);
the preflight.sh rationale is stated once rather than in two comment blocks;
the Go test locates the shell script relative to its own source file; and the
gofmt step takes GOPROXY=off like its neighbours.

# Credential pre-flight for the agentic reviewer, in ONE definition.
#
# Sourced by run.sh (production) and by preflight_test.sh (the table test), so
# the tested bytes and the running bytes are the same. Keep it that way: a test
# that reimplements this logic can agree with a stale copy of it.
#
# Why pre-flight at all, when majordomo already fails closed with a 401:
# without it a missing key surfaces as five identical per-lens agent failures
# that name no variable, and the operator reads a stack trace to learn which
# secret they forgot to forward.
# gadfly_preflight_key <provider> -> echoes "" when the run may proceed, or the
# name of the environment variable the operator must set.
#
# Scope: the REGISTRY path only — GADFLY_BASE_URL unset — and deliberately so.
# The two resolution paths have DIFFERENT credential rules: with an explicit
# endpoint the credential is GADFLY_API_KEY (falling back to the client's own
# default, OPENAI_API_KEY for the openai family) and a built-in's own variable
# is never consulted; without one, the reverse. Applying either path's rule to
# the other yields a check that passes a run which then 401s — the precise
# failure this exists to prevent. So it covers the path whose rules it can state
# exactly and stays silent on the other. That is also the useful half: an
# override-path config is hand-written, while the registry path is what somebody
# hits by adding a model id to a var and forgetting the secret.

# 2. It needs a key but accepts more than one variable, so a single-name check
# would skip a correctly-configured run. **google** is this case
# (GOOGLE_API_KEY *or* GEMINI_API_KEY); pre-flighting it needs an
# either-variable check, not this table's one-name shape.
