Upgrade to 1.0.0-rc830

Concerns: pushword/static-generator

The opcache file cache moved under var/cache/opcache/w{n}

pw:static used to point every parallel worker at one shared var/cache/opcache. Concurrent processes writing a single opcache file cache segfault the workers on some PHP builds (reported on CloudLinux alt-php 8.4.3: 6 workers out of 8 killed on every run, exit 139). Each worker now writes its own directory.

Nothing to run: the new directories are created on the next build. Two things to know:

• The old shared entries are now orphaned — delete var/cache/opcache once to reclaim the space (safe at any time; the next build refills what it needs).
• Disk grows to roughly one full compiled-code cache per worker. If the build machine is tight on disk, cap the workers with pw:static --workers=N.
