fix: batch-eval docs + preserve config-bundle placeholders on AB-test promote

[jariy17]

Two independent bug-bash fixes, one commit each.

1. fix(docs): remove non-existent Builtin.Completeness evaluator

The batch-evaluation docs listed Builtin.Completeness and used it in a CLI example, but the API rejects it (Builtin evaluator Builtin.Completeness does not exist). The valid builtin list lives in run-eval.ts and never included it.

• Dropped the row from the evaluator table in docs/batch-evaluation.md
• Switched the dataset example in docs/commands.md to Builtin.Correctness

2. fix(ab-test): preserve portable component placeholders on promote

config-bundle promote fetched the winning version's components from the service — which keys them by resolved (account/region-specific) runtime ARN — and wrote them straight into agentcore.json, replacing the committed {{runtime:<name>}} placeholders with hardcoded ARNs and breaking cross-account/region portability.

Before: "{{runtime:cbagent}}" → after promote: "arn:aws:bedrock-agentcore:us-west-2:...:runtime/cbbugbash_cbagent-N5owhv3MRl"

Fix: restorePlaceholderKeys() inverts the local bundle's placeholder→ARN map (using the same resolver deploy uses) and rewrites each incoming ARN key back to the placeholder before adopting. ARNs with no matching local placeholder pass through unchanged.

Testing

• promote.test.ts: added a case asserting an ARN-keyed service response is rewritten back to {{runtime:r}} and the ARN key is absent. 13/13 pass.
• typecheck + prettier + eslint pass (pre-commit hooks).

Claude Security Review: no high-confidence findings. (run)

[agentcore-cli-automation]

LGTM — two well-scoped, independent fixes with appropriate test coverage.

Docs fix: Verified Builtin.Completeness is not in BUILTIN_EVALUATOR_LEVELS in src/cli/operations/eval/run-eval.ts (only Correctness, Faithfulness, Helpfulness, ResponseRelevance, Conciseness, Coherence, InstructionFollowing, Refusal, GoalSuccessRate, ToolSelectionAccuracy are listed). Removing the row and swapping the example to Builtin.Correctness is correct.

Promote placeholder fix: restorePlaceholderKeys correctly inverts the local placeholder→ARN map by reusing the same resolveComponentKeyForJsonPath resolver the deploy/recommendation paths use, so behavior stays consistent. Skipping local arn:-prefixed keys and the arn !== key guard (unresolved placeholders) are both right. Pass-through for unmatched service ARNs is a reasonable fallback.

Test quality: Good — the new test only mocks at true I/O boundaries (ConfigIO, getConfigurationBundleVersion) and exercises the real resolver. Not excessively coupled to implementation.

No telemetry needed since this is a bug fix on a path that doesn't currently emit telemetry.
