v0.3.0

Changed

• Breaking: Migrated to the provider/model registries OpenCode 2.0.4
  introduced in #48901, which
  removed the catalog plugin domain. Provider and model registration now runs
  through ctx.provider.transform, and revalidation reloads via
  ctx.provider.reload(). This release requires OpenCode 2.0.4 or newer; on
  2.0.0–2.0.3 it fails to load with
  undefined is not an object (evaluating 'ctx.provider.transform'). Stay on
  0.2.x for those versions.

• A startup with no cached catalog now waits for the first discovery before
  handing control back to OpenCode, capped by the new coldWaitMs option
  (default 3000). Stale-while-revalidate previously returned immediately even
  with nothing to serve, so OpenCode activated the plugin against an empty
  catalog. Short-lived invocations such as opencode run -m cliproxyapi-.../...
  failed with Model unavailable and exited before the discovery that would
  have populated the cache ever completed, leaving every subsequent run equally
  cold. A warm cache still registers immediately and revalidates in the
  background, and discovery that outlives the cap still registers when it
  lands.

• A model metadata outage can no longer degrade the cached catalog. With a
  healthy CLIProxyAPI and an unreachable models.dev, every model fell back to
  default names, limits, modalities, and protocol, and that reading was written
  to the cache, so the loss survived a restart until metadata happened to come
  back. Models that metadata did not describe now keep their last enriched
  definition, matching how reasoning variants are already preserved.

• Discovery failures are now reported to OpenCode's logs when discovery starts
  failing and again when it recovers. A failure is otherwise invisible by
  design, since the cached catalog keeps serving, which left a stale catalog
  with nothing explaining it. Only the transitions are logged, so a server that
  stays down does not add an entry per poll.

• The plugin now builds against the published @opencode/plugin package
  (OpenCode 2's own plugin package) instead of the @opencode-ai/plugin
  prerelease, so the V2 domains are properly typed.
