fix(javascript): retain standalone GraphQL source operations

Retain named operations in GraphQL Source bodies with locationOffset metadata.
Use final property ownership and parsed lexical facts to suppress copies only
when a recovered document, its containers and source aliases have proven
private metadata ownership. Preserve independent observations after writes,
exports, opaque uses, classic-script global exposure or direct evaluation.

Share interpretation across application and captured-web analysis. Build
optional reference indexes once per source and checkpoint examined records,
including suppressed findings, to retain cooperative cancellation.

Fixes #3311
