* fix(ci): base64-encode zuey SSH key secret to dodge libcrypto error
First real deploy_zuey_beta run failed at the new 'Sync zuey ops scripts
to VPS' step with 'Load key: error in libcrypto' / Permission denied,
because GitHub Secrets storage normalized newlines inside the multi-line
PEM block.
Switch the secret to ZUEY_SSH_PRIVATE_KEY_B64 (single-line base64) and
base64 -d it on the runner. Single-line storage is immune to whitespace
mangling. Add a ssh-keygen -y -f pre-flight check that fails fast with
a clear remediation message if either the base64 or the decoded key is
malformed.

* fix(ci): create SSH key at 0600 from birth via umask 077
Defense-in-depth from review of PR #79: wrap the base64-decode pipeline
in a subshell that sets umask 077 so the decoded private key file is
created at 0600 directly, instead of relying on a chmod 0600 after the
fact (which left a brief 0644 window).
* feat(ci): deploy zuey beta releases
Add automatic zuey VPS deployment to the dev beta release workflow after prerelease assets are published. Publish beta checksums and make the host upgrade script tolerate beta asset naming and checksum fallback.
* fix(deploy): allow active beta release reruns
Treat an existing target release as success only when it is already the active release and still contains the expected binary and migrations. This keeps automated beta deploy reruns from failing after a prior successful deploy while preserving fail-closed behavior for stale or partial release directories.
