Add getGitRepoInfo() to DaemonClient + E2E tests

- Added getGitRepoInfo(agentId) method that returns repo info (branches,
  currentBranch, isDirty, repoRoot) by looking up the agent's cwd and
  sending git_repo_info_request
- Added 3 E2E tests: (1) returns repo info for git repo with branch and
  dirty state, (2) returns clean state when no uncommitted changes,
  (3) returns error for non-git directory
