linkml_model/graphql/meta.graphql shipped in the linkml-runtime wheel does not parse #67

packages/linkml_runtime/src/linkml_runtime/linkml_model/graphql/meta.graphql is shipped inside the linkml-runtime wheel and does not parse:

from graphql import parse
import pathlib
parse(pathlib.Path("packages/linkml_runtime/src/linkml_runtime/linkml_model/graphql/meta.graphql").read_text())
# graphql.error.syntax_error.GraphQLSyntaxError: Syntax Error: Unexpected Name 'Extensible'.

The cause is the comma-separated implements clause that #63 fixes in the generator: ImplementsInterfaces joins with & (GraphQL spec, October 2021, §3.6). Regenerating the file with the fixed generator would make it parse, though the remaining gaps in #64 and #66 would still apply to it.

Two other committed artifacts are in the same state:

• examples/PersonSchema/personinfo/graphql/personinfo.graphql — Syntax Error: Unexpected Name 'HasNewsEvents'. Also stale for unrelated reasons (metamodel 1.7.0).
• examples/organization.graphql — orphaned; examples/organization.yaml no longer exists.

No test or CI job consumes any of them (.github/, Makefile, pyproject.toml checked; Makefile is the only generator reference), so nothing is currently broken by it. #63 deliberately left all three alone to keep its diff to the generator and its tests.

The question for meta.graphql specifically is where it should be regenerated: it looks vendored from linkml/linkml-model rather than produced by this repository's build, in which case the fix belongs there and this repository only re-vendors.
