v1.4.0: Upgrade to hypersync-client 1.3.0 (streaming v2) (#64)

* Upgrade to hypersync-client 1.3.0 (streaming v2)

- Bump hypersync-client 1.1.4 -> 1.3.0.
- StreamConfig: drop response_bytes_floor/ceiling; make max_batch_size an
  optional no-cap (None => no block cap); add response_bytes_target (default
  400000) and max_buffered_bytes (None => adaptive). Update the From impl and
  index.d.ts.
- get_with_rate_limit: adapt to the new RateLimitResponse enum — response is
  now optional (null on HTTP 429); inspect rate_limit and retry.

* Bump to 1.4.0 and regenerate napi artifacts + typedoc docs

- package version 1.3.0 -> 1.4.0 (1.3.0 already on npm); synced the npm/*
  platform sub-packages via 'napi version'.
- Regenerated index.d.ts / index.js from the 1.3.0 build (yarn build) and the
  typedoc HTML under docs/ (yarn docs) — StreamConfig now shows
  response_bytes_target / max_buffered_bytes and the optional rate-limited
  response.

Built against published hypersync-client 1.3.0; release/publish runs in CI.
