Two workspace+services command files converted, batched because they share
the same pattern (4 stars each -> selective).
workspace/commands.nu:
user/config.nu [11 symbols]
utils/hints.nu [show-next-step]
platform/activation.nu [activate-workspace-platform]
workspace/notation.nu [3 symbols]
Pre-existing name collision documented: get-workspace-path and
list-workspaces are exported by BOTH user/config.nu and notation.nu.
Star-import resolved via last-wins (notation.nu). Selective version
attributes both to notation.nu to preserve behaviour.
services/commands.nu:
services/manager.nu [9 symbols]
services/health.nu [2 symbols]
services/preflight.nu [4 symbols]
services/dependencies.nu [5 symbols]
Validation: both files nu --ide-check 50 -> 0 errors.
