fix(lint): resolve no-unused-vars errors flagged by CI

- bounded-retry.ts:103 — drop unused generic parameter <T> from
  BoundedRetryOptions interface (and its single use at line 220).
  The generic served no purpose: the caller's return type is inferred
  from the operation function, not from the options.
- retry-utils.test.ts:5 — remove `beforeEach` from imports. It was
  only used by the RetryManager describe block, removed in commit
  0f2402da58.

Build clean, 58 tests pass (12 bounded-retry + 46 retry-utils).
