test(deploy): add workspace deploy unit tests and e2e test

Add unit tests for workspace deploy edge cases:
- all-library workspace correctly errors with "No deployable workspace
  members found"
- mixed library+program workspace builds only the program member

Add test helpers `sample_workspace_all_libraries` and
`sample_workspace_mixed` to support the above.

Add e2e integration test `test_workspace_deploy` that deploys a
two-member workspace (token + swap) against devnode, exercising build
ordering, shared-dep dedup, workspace deployment plan output, and
end-to-end broadcast confirmation.
