fix(opencode): bill OpenCode Go requests from the reported list_cost (#48254)
* fix(opencode): bill OpenCode Go requests from the reported list_cost

OpenCode returns usage.opencode.list_cost on every response. Read it into the provider-reported cost the cost calculator checks before the price map, for chat and Responses, streamed and not. Keep the static rows as the fallback, and stop the generic usage.cost path from billing Go requests at 0 (usage.cost is what hit the prepaid balance, 0 inside the plan).

* fix(core): resolve reported cost breakdowns without recursion

* test(opencode): cover reported list_cost spend through the proxy

Replaces the recursive _reported_cost_value with a flat _cost_number helper
so the code-quality gate passes, and adds an integration test that runs the
proxy against a scripted OpenCode upstream for a non-stream and a stream
chat completion, asserting the response cost header and the spend log row

* fix(opencode): bill native /v1/messages from the reported list_cost

The native Anthropic Messages route priced OpenCode Go bodies from the price
rows twice over: the non-stream body is a TypedDict the response-cost header
path priced as-is, and the stream assembled its ModelResponse with the rows
cost already stamped. Both now read usage.opencode.list_cost, the non-stream
body through billable_result and the stream from the final message_delta.

The integration test now covers chat, responses and messages, stream and
non-stream, through the proxy against a scripted OpenCode upstream

* fix(opencode): keep the stream cost stamp inside the lint gate

* fix(opencode): read list_cost off dict chunks and trust it only from OpenCode on /v1/messages

Stream builders receive chunks both as mappings and as ModelResponseStream
objects, so the list_cost scan now reads usage through chunk_usage. The
native Messages route only trusts a reported cost from opencode_go, every
other upstream keeps the price map, which also keeps a zero usage.cost from
being billed as free. Served bodies without stop_sequence still price, and
the new code stays inside the basedpyright gate
