chore: sync Go client with Apify OpenAPI spec v2-2026-06-30T091455Z

Version-only sync from v2-2026-06-29T142258Z. An independent operation- and
parameter-level audit of the new spec (131 paths / 231 operations), with the
apify-client-js reference as the in-scope parity authority, found no change to
the in-scope API surface. Bumps the version constants to 0.4.3 (patch) and
fixes documentation/changelog consistency flagged by review.

- version.go: API_SPEC_VERSION -> v2-2026-06-30T091455Z; CLIENT_VERSION -> 0.4.3
- CHANGELOG.md: [0.4.3] entry (API_SPEC_VERSION, CLIENT_VERSION, README sync)
- README.md: Versioning section spec version synced to version.go
- docs/actors.md: document nil waitSecs behavior for Call

+
+Synchronized with Apify OpenAPI specification `v2-2026-06-30T091455Z` (previously
+`v2-2026-06-29T142258Z`). An independent operation- and parameter-level audit of the new
+specification (131 paths / 231 operations) against the exposed client surface — with the
+`apify-client-js` reference client as the parity authority for which endpoints are in scope — found
+**no change to the in-scope API surface**: same paths, operations, query/header parameters, request
+bodies and response schemas. Spot-checks of the highest-churn endpoints (`POST /v2/actors/{actorId}/runs`,
+`GET /v2/store`, `GET /v2/datasets/{datasetId}/items`, `GET /v2/actor-runs` including the
+`startedAfter`/`startedBefore` filters, `POST /v2/actor-runs/{runId}/charge`,
+`POST /v2/actor-runs/{runId}/resurrect`) confirmed every documented parameter remains covered. The
+endpoints not exposed by the client (`run-sync` / `run-sync-get-dataset-items`,
+`/v2/tools/encode-and-sign` & `/v2/tools/decode-and-verify`, `/v2/browser-info`, and the keyed `POST`
+create variants that duplicate the covered `PUT` writes) remain out of scope, matching the reference
+client. No public API surface change, so this is a patch release.

+### Changed
+- Bumped `API_SPEC_VERSION` to `v2-2026-06-30T091455Z`.
+- Bumped `CLIENT_VERSION` to `0.4.3` (patch; spec-sync only, no public API change).
+- Updated the `v2-2026-06-29T142258Z` reference in the `README.md` "Versioning" section to
+  `v2-2026-06-30T091455Z` so it matches `version.go`.
