xray-core 26.11.9 (#7329) renamed a final rule's blockDelay to delay, added
logLevel, and now refuses either on a rule whose action is not block. A
stored template with a blockDelay on an allow rule therefore stops the core
at startup after the upgrade.
A one-time seeder strips delay, blockDelay and logLevel from non-block rules
of the template's freedom outbounds and moves blockDelay to delay on block
rules. The outbound form reads both spellings (blockDelay wins, as in the
core), writes delay, gains a log level control on block rules and emits
neither key on an allow rule.
