Pull request overview
This PR continues the ongoing Jest→Vitest rule split by extracting prefer-to-contain into shared logic and introducing a dedicated vitest/prefer-to-contain rule, removing it from the “vitest compatible jest rules” compatibility list.
Changes:
- Remove
prefer-to-containfromVITEST_COMPATIBLE_JEST_RULESand the synced JSON list. - Factor the rule implementation into a shared
rules::shared::prefer_to_containmodule and wire bothjest/andvitest/wrappers to it. - Add Vitest-specific snapshots and register the new Vitest rule in generated rule registries.

…ule. (#21821) Part of #21664. Generated with Claude Code, Opus 4.7. Reviewed by me. I had Claude double-check itself after simplifying the vitest tests down, and manually spot-checked 8 different tests in the vitest snapshot to make sure the deleted tests were indeed duplicates. All were identical dupes of other tests in the same file.
