Squash of Gosalyn's 96768766c on gosalyn/c2-13a-r2 (base 722136772), the
5 manifest paths, build.patch 56649f9a, manifest fbb0d7e42c67 (Webby
approve round 2, rev 2563). Gosalyn's gate on 96768766c: cli 541 pass
0 fail; scripts/test-*.sh 429 pass 0 fail (summed by script); mutants
10 of 10 killed. packages/cli/README.md is a 3-way merge with row 199
(cb5fdb064): the hunks don't overlap (line 710 vs 1022). host.test.mjs:855
is the only test that reads that file. On cb5fdb064 plus the patch,
case2-unit.test.mjs 30/0 and host.test.mjs 42/0. Refactor moved to
390ea5261 since, a README fix touching no manifest path. The script
runs on a host only in a separate window with Jason's go.
