fix(maker): slow down clone transient retries

- Increase Maker clone/fetch retry budget from 2 to 3 retries.

- Change default retry base delay from 1500ms to 10000ms.

- Give Maker repositories more time to finish server-side preparation.

- Cover retry count and default delay with clone binding tests.

- Update Maker docs for the new retry behavior and env override default.

Verification:

- npm test -- --runTestsByPath src/__tests__/makerCloneBinding.test.ts --runInBand

- npm run lint

- npm run format:check

- npm run build

- npm test -- --runInBand
