Soak release candidates for 24 hours before stable

The resolver refused a stable promotion until its candidate had soaked for
72 hours, or 168 for a minor. Few installs run previews: 35 of about 7,900
active installs ran v6.4.5-rc.3 in the week to 2026-09-28, so a longer
soak saw little the first day did not, while 75 percent of installs sat on
a stable build a month old. Richard set a 24 hour soak for every release
on 2026-09-28.

The minimums drop to 24 hours for minor and patch alike, the error text
reads the constants instead of repeating numbers, and the workflow and
trigger prompts, the promotion policy and the deployment contract say the
same. The content-drift check and the hotfix exception are unchanged.
