fix(merge): round-2 CI failures — pipefail sites, verify:release mirror, format

Pipeline 2534 (018d96a), two test-step failures plus the format failure
root-caused by rev-code-01 (id 202):

1. pipefail-early-exit.test.mjs: main's window wrote the test but never
   wired scripts/*.test.mjs into its own CI, so its tools/install.sh pipes
   were never executed against it; next's test wiring runs them and flags
   two load-bearing pipes. Both rewritten pipefail-safe via process
   substitution (newest_matching_file ls|head, check_fleet_transport
   sed|head|tr|awk). Test now 7/7 locally.

2. verify-release.test.mjs: merge kept main's 9-command ci.yml sanitization
   but next's 4-command canonical stage. Canonical updated to mirror ci.yml
   exactly (9=9, order verified). upgrade-guard checked equal (4=4).

3. format: docs/reports/quality/1099-pipefail-sweep.md (from main f158be8)
   prettier-formatted under pinned 3.8.1.

Enumeration guard re-verified: population 60, enumerated 45, excluded 16.
