chore: sync deprecated ITS pipeline copy

[dheerajodha]

Summary

• add a sync/check helper for the deprecated build-definitions Enterprise Contract ITS pipeline copy
• wire the existing build-definitions update helper to run the pipeline sync before updating bundle refs
• document the manual sync/check flow and digest-pin preservation behavior

Testing

• bash -n hack/sync-build-definitions-pipeline.sh
• bash -n hack/update-build-definitions.sh
• git diff --check
• temp build-definitions sync/check flow, including preserving existing bundle digest refs
• make lint attempted; failed because npm is not on PATH and Podman is not reachable at 127.0.0.1:49531 on this machine

📝 Walkthrough

A new script checks or syncs the deprecated Enterprise Contract pipeline copy in build-definitions. The release-promotion script runs the sync before updating task bundle references. The README documents the source of truth and sync options.

Changes: Deprecated pipeline synchronization

Layer / File(s)	Summary
Sync setup and pipeline generation hack/sync-build-definitions-pipeline.sh	The script defines source and target paths, parses options, validates the checkout and yq, and prepares a temporary pipeline file with a deprecation notice. It preserves existing task bundle references by default when matching source and target values are present.
Check, write, and release update hack/sync-build-definitions-pipeline.sh, hack/update-build-definitions.sh, acceptance/README.md	Check mode reports whether the target matches and displays drift. Normal mode writes the generated file. The release-promotion script runs the sync before updating bundle references across tasks. The README documents the source, options, and workflow.

Risk Assessment: low (1/5)

Details

This PR adds documentation and tooling-only artifacts (a new shell sync script and acceptance README updates) with no protected paths, no security-sensitive code, no CI or dependency changes, and a consistent low-risk git history on the touched files.

Risk Assessment: low (1/5)

Risk Assessment: low (1/5)

Details

Same-SHA re-review: Tier 1 signals unchanged from prior assessment; code-age staleness of update-build-definitions.sh was already accounted for; churn signal on acceptance/README.md reflects the PR's own commits rather than independent hotspot activity; re-review anchoring preserves prior score of 1.

Previous run (3)

Risk Assessment: low (1/5)

Details

Small 3-file docs-and-scripts PR by an established contributor with no protected paths, no security-sensitive files, no CI or dependency changes; mild elevation only from staleness of update-build-definitions.sh (~487 days). Composite 1.40 rounds to 1.

Review comments at @hack/sync-build-definitions-pipeline.sh:
- Around line 140-148: Update the rewrite in the bundle-processing loop so it
changes only the bundle pin for the current task instead of replacing every
occurrence of a shared source bundle and skipping later tasks. Use the
task-specific identity and its bundle value to target that task’s bundle
reference, preserving distinct pins in standalone sync targets and making write
mode and --check agree.

hack/sync-build-definitions-pipeline.sh: 2

139-151: This is the same concern as the earlier review comment. The perl substitution is scoped per task, so it does not replace every occurrence with the first task's pin. The deduplication loop from the earlier comment is no longer in this code. Distinct pins are preserved per task.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Declare and assign ROOT separately.

Shellcheck SC2155 reports that readonly masks the exit status of the command substitution. Assign first, then mark readonly. The same applies to line 22 only; other readonly uses are plain values.
