Generalize the release-age quarantine into a manifest policy

Move the hold from a mise-only hardcode to min_release_age in
.omarchy/package.json ("24h", "2d", or bare seconds), alongside source and
release_ring where package policy already lives. bin/sync-upstream exports
the window to every hook as MIN_RELEASE_AGE_SECONDS so a hook that can walk
its release feed selects the newest release that has cleared it, and
enforces it as a backstop: with a policy set, the hook must report
published_at, and a release younger than the window is treated as no
update. A hook that cannot prove the age fails the sync rather than
shipping unverified. BYPASS_MIN_RELEASE_AGE=1 replaces the package-specific
bypass for deliberate emergency updates; scheduled automation never sets it.

The mise hook keeps its release-list walk but reads the window from the
environment and reports published_at; the other upstream hooks are
untouched and unaffected until they opt in.

+A package may declare "min_release_age" in .omarchy/package.json ("24h", "2d",
+or bare seconds) to quarantine fresh releases until maintainers have had time
+to pull a bad or compromised one. The window is exported to the hook as
+MIN_RELEASE_AGE_SECONDS so it can select the newest release that has already
+cleared it, and enforced here as a backstop: the hook must then report
+"published_at" (ISO 8601), and a release younger than the window is treated
+as no update. A maintainer shipping an emergency update inside the window
+runs: BYPASS_MIN_RELEASE_AGE=1 $0 <package>. Scheduled automation never sets
+the bypass, so the resulting change still goes through a reviewed PR.
