tests: runner test for skipDuplicates immutable entities

isum · isum · commit 3a426e4435eb · 2026-03-26T16:36:36.000+02:00
Add end-to-end runner test exercising @entity(immutable: true, skipDuplicates: true) with duplicate entity inserts across blocks. - tests/runner-tests/skip-duplicates/: subgraph with Ping entity using skipDuplicates, block handler that saves same ID every block - tests/tests/runner_tests.rs: skip_duplicates() test syncs 4 blocks and verifies entity is queryable (indexing did not fail)
