This commit introduces the `no-unnecessary-condition` rule to the linter, which detects unnecessary conditional expressions in TypeScript code. The rule is implemented in `no_unnecessary_condition.go` and is accompanied by comprehensive tests in `no_unnecessary_condition_test.go`. The rule checks for always truthy or falsy conditions, unnecessary optional chaining, and allows configuration for constant loop conditions.
This commit expands the `no-unnecessary-condition` rule by adding new checks for unnecessary conditions, including handling of the `never` type, literal comparisons, and type overlap in equality operations. It also introduces new messages for specific cases, improving the rule's ability to detect unnecessary conditional expressions in TypeScript code. Comprehensive tests have been updated to cover these new scenarios.
