Problem

coder exp sync want and coder exp sync start both printed generic success messages, which hid the dependency units involved in startup coordination.

Before, declaring dependencies with sync want printed:

Success

Before, sync start printed while waiting, then finished with another generic success message:

Waiting for dependencies of unit 'test-unit' to be satisfied...
Success

Solution

Print the dependency units in both cases, using wording that matches where the command is in the lifecycle.

After, sync want prints the dependencies it declared for the unit:

Unit "test-unit" declared dependencies: [dep-unit]

After, sync start enumerates the dependencies while it is waiting, then prints the same dependencies after the unit starts executing:

Unit "test-unit" is waiting for dependencies to be satisfied: [dep-unit, dep-unit-2]
Unit "test-unit" finished waiting for dependencies: [dep-unit, dep-unit-2]

The sync golden tests now cover the updated output, including multiple dependencies for sync start.
