feat(kenari): add Kenari as a first-class provider (#793)

* feat(kenari): add Kenari as a first-class provider

* test(kenari): cover provider registration arms and stream branches

* test(kenari): flip remaining partial branches, drop dead reasoning fallback

* refactor(kenari): address review feedback

- Reuse the shared extractReasoningFromDelta helper in the stream handler
  instead of a hand-rolled reasoning_content cast, matching opencode-go;
  this also adds the OpenRouter-style `reasoning` fallback. New handler
  test covers the fallback path.
- Fetcher spec: assert the surviving entry's contextWindow in the
  skip-invalid test so a field-mapping regression in that branch is
  caught, and add a parseKenariModel test that locks the
  context_window/max_output_tokens precedence over their aliases.
- Hoist KENARI_BASE_URL into @roo-code/types so the handler baseURL and
  the fetcher endpoint share one source of truth.
