Add TooManyMigrationRuns cop to test performance#4850
Draft
Conversation
Enforces max 4 migration runs per test file to prevent expensive repeated migrations. Detects subjects, let helpers, helper methods, and before/after blocks. Intentionally simple to avoid false positives on edge cases. Also reduce number of migration calls in `_add_state_to_stacks_spec` & `bigint_migration_step1_shared_context` to please Rubocop.
