v3.0.0

End-of-life dependency remediation. Client methods, arguments, and return values are
unchanged — most codebases upgrade with no code changes. See
MIGRATING-v3.md for a full before/after guide.

⚠️ Breaking Changes

• Node.js 22 is now required (engines: ">=22"). Node 18/20 are end-of-life.
• Error message format changed. Replacing Apollo Client 2 with @apollo/client 3
  drops the "Network error: " prefix on network errors — a failed request now throws
  e.g. Response not successful: Received status code 401. Only affects code that matches
  on the error message string.
• logger option type changed from the bunyan-category Logger to an exported
  structural Logger interface ({ trace, debug, info, warn, error, fatal }). Any
  bunyan/pino-style logger still satisfies it, so passing an existing logger keeps working.
  The default logger is now pino (JSON output, no category field).
• Apollo type import source moved from apollo-client to @apollo/client/core
  (affects client.graphClient and other directly-imported Apollo types). Related type-only
  renames: queryGraphQL returns InteropApolloQueryResult (same shape as
  ApolloQueryResult); QueryResults<T>.errors elements are GraphQLFormattedError.
  Runtime shapes unchanged.
• CLI YAML parsing uses the YAML 1.2 schema (js-yaml 3 → 4). Unquoted scalars like
  0777 (now decimal 777, was octal 511) and 12:30 (now a string, was 750) resolve
  differently. Affects j1 CLI .yml/.yaml input only. See MIGRATING-v3.md §5.

Changed

• Replaced apollo-client + apollo-cache-inmemory + apollo-link* (EOL) with
  @apollo/client 3, and graphql 14 → 16.
• Replaced bunyan-category with pino, removing the deprecated
  mv → rimraf → glob → inflight dependency chain.
• Upgraded toolchain: TypeScript 3.8 → 5, Jest 27 → 30, ESLint/@typescript-eslint,
  js-yaml 3 → 4; migrated the package manager from Yarn to npm; pinned CI to Node 22.
• Production npm audit: 322 → 0 vulnerabilities.
