Add Mocks & Tests

[TrevorJTClarke]

GOAL:

Setup a way to have "E2E" testing to ensure new code doesnt break previous functionality. Add unit tests to cover basics, add mocks for helping aid replicable flows.

Requirements:

• [ ] Setup unit tests for covering basics like block / pipeline flow, orderliness
• [ ] Setup E2E mocks (lib? see how strangelove does it with IBC & sdk mock) for mocking RPC
• [ ] Setup flows that mock the entire lifecycle of an agent:
  • [ ] Register
  • [ ] Do 3-6 tasks
  • [ ] withdraw rewards
  • [ ] Unregister
