…ces [DX-9469]

pendingVariantAndVariantGrpForExperience was populated with ALL created
experience UIDs regardless of whether valid variants were submitted to the
API. Experiences with variants:[] never get variant groups from the
Personalize backend, so the validation loop timed out and set
importData=false, skipping attachCTsInExperience for every experience
including valid ones.

Fixed by:
1. Adding a versionMap guard in importExperienceVersions (returns boolean)
   so only experiences that actually submitted variants return true
2. Only adding UIDs to the pending set when importExperienceVersions
   returns true
3. Adding a null guard in attachCTsInExperience before accessing
   variantGroup to prevent a silent crash inside Promise.allSettled

Note: Bug 2 (missing data-for-variant-entry.json) is not present in v2
— processCleanup always calls createEntryDataForVariantEntry regardless
of environments.

- Add 11 test cases covering importExperienceVersions returning false
  for missing file, Lytics-only audiences, and unmapped CS audiences
- Add tests verifying Set-based pending list only includes experiences
  with valid variants submitted to Personalize
- Add tests for validateVariantGroupAndVariantsCreated resolving
  immediately when pending list is empty
- Add tests for attachCTsInExperience null guard skipping gracefully
  when variantGroup is missing
- Fix mocha-root-hooks.js to guard loadChalk as optional (not exported
  in current cli-utilities version)
- Fix importExperienceVersions to return false (not undefined) when
  versions file does not exist, for consistent boolean API

Message was blaming Lytics audiences specifically but the branch fires
for any mapping failure (CS or Lytics). Broadened to "after
audience/event mapping".

…orts [DX-9469]

Both were made redundant by the Set-based pending list introduced in the
DX-9469 fix. Leaving them risks build failures under noUnusedLocals or
ESLint unused-import rules.
