- Fix assert_receive timeouts < 1000ms across 8 test files
- Move nested import statements to module-level scope
- Fix tests with no assertions and add missing doctest
- Replace weak type assertions with specific value checks
- Fix conditional assertions and length/1 expensive patterns
- Disable inappropriate Jump.CredoChecks.AvoidSocketAssignsInTest
- Fix tests not calling application code with credo:disable
- Add various credo:disable comments for legitimate patterns
