gate: Claude Code behind it — OAuth bearer, anthropic-beta, token counting, the gate's own watch

A coding agent's traffic differs from a hand-made request: with a
subscription Claude Code authenticates with an OAuth bearer and sends
anthropic-beta; it counts tokens at /v1/messages/count_tokens; it makes a
request per tool call; its tool-only turns have no text; its context runs
to megabytes. So: with the courtyard key in X-Bikoret-Key, the caller's
Authorization: Bearer is forwarded to Anthropic as its credential, and
anthropic-beta with it; count_tokens is carried through unexamined and
uncharged; the watch counts the gate at its own windows (120/min,
2,000/h per key — tier :gate); a reply with no text is delivered as it
came with bikoret.verdict "none" and no fringe block (stream and
non-stream); the sources keep the newest user turns whole and drop the
oldest past 1 MiB. Ingress body 32 MiB; ConfigMap manna amounts raised
to 5000/5000 (the kohen's lever). Tamid §1.1, KOHEN "Claude Code behind
the gate". Doorpost re-pinned. Elixir 617/0 read before this commit;
gate_test 25.
