refactor(15 single-star batch 3): selective imports + dead drop (ADR-025 L2)

15 files. Most are dead `use ../config/accessor.nu *` imports dropped.

Selective imports:
  setup/utils.nu                 config/accessor/functions [get-providers-path]
  setup/detection.nu             setup/mod [8 symbols]
  plugins/secretumvault.nu       config/accessor/core [config-get]
  plugins/orchestrator.nu        config/accessor/core [config-get]
  kms/client.nu                  utils/error + utils/interface + plugins/kms
  deploy.nu                      result.nu [7 symbols]
  dependencies/resolver.nu       config/loader [get-config]

Dead imports dropped:
  setup/config.nu                config/accessor
  extensions/profiles.nu         config/accessor
  extensions/loader.nu           config/accessor
  workspace/init.nu              config/accessor
  utils/help.nu                  config/accessor
  utils/error_fixed.nu           config/accessor
  utils/error_clean.nu           config/accessor
  utils/error_final.nu           config/accessor
  dependencies/resolver.nu       oci/client

Validation: all 15 match or IMPROVE baseline:
  - 11 files: 0 errors
  - utils/error_fixed  4 -> 1  (IMPROVED)
  - utils/error_clean  4 -> 1  (IMPROVED)
  - dependencies/resolver  50 = 50 (unchanged pre-existing noise)
  - deploy.nu          19 = 19 (unchanged; file is orphaned — zero importers)
