0.1.0

First release, published to npm as dsh-llm-opencode-go.

Added

• Provider route — OpenCode Go (https://opencode.ai/zen/go/v1) registered on
  the harness LLM runtime under the opencode-go route id (configurable), with a
  runtime health check that reports the base URL and credential reference.
• Three wire protocols — OpenAI Responses, OpenAI-compatible Chat Completions,
  and Anthropic Messages, each implemented by the plugin: harness messages, tools
  and reasoning are translated into the protocol's request, and its streamed
  response is translated back into DSH StreamChunk values.
• Model discovery — GET /models with an in-memory and an on-disk cache, a
  built-in fallback catalog, and per-model protocol selection measured against the
  live service.
• x-opencode-session — one stable id per conversation, derived from the DSH
  session id by default, which is what keeps a conversation's turns on the same
  upstream backend and the same prompt cache.
• Tool calling — a full round trip for every dispatched call: definitions,
  fragmented arguments, tool results, and the follow-up turn.
• Reasoning — per-protocol effort mapping, including Anthropic thinking budgets.
• Streaming — SSE to StreamChunk with usage, finish reason, and an idle
  watchdog.
• Failures — provider-neutral codes (AUTH, RATE_LIMIT, QUOTA,
  CONTEXT_WINDOW_EXCEEDED, …) so the harness can act on a failure without knowing
  which protocol produced it.
• Configuration page — a page in the web client's Plugins list: API key,
  credential reference, per-model visibility, model variants, re-reading the
  service's model list, and what this route has spent. The key goes to the
  credential store, never into cordis.patch.yml.
• Usage entries — the quota capsule at the sidebar's foot (one ring per window:
  5H / Wk / Mo), a usage panel of its own, and a usage tab under Settings.
• Test suites — 326 offline checks across config, SSE framing, catalog, all
  three protocols, the adapter, the plugin body, the settings bridge and the client
  bundle, replaying response bodies captured from the live service
  (tests/golden/); 43 further checks mounting the plugin on the harness's own
  cordis; and a live suite that spends real quota.
• Zero runtime dependencies — the adapter implements the harness contract with
  its own error and brand helpers, so it installs into any DSH version.
