7.6.1

• Fixed a race in Queues\Adapter\DbAdapter::getMessages() that could hand the same message to two consumers at once (Trello nIjO2cqy). Candidate ids were prefetched without a lock and then claimed with FOR UPDATE SKIP LOCKED, which only skips rows still held by an open transaction — a competing consumer that had already claimed and committed one of those ids got it delivered a second time, and receive_count was bumped twice. The availability conditions (time_in_flight, delayed_until, receive_count, priority) are now re-evaluated inside the locking read, which is also ordered by added_at so the oldest candidates are taken first.
• Note for queues on DbAdapter: the default timeInflight is 0, which makes a claimed message visible again after 1 s regardless of this fix. Set a meaningful timeInflight if a message must not be redelivered while it is being processed.
• Ticker: fixed implicit float-to-int conversions (result keys and usleep() argument) that raise a deprecation on PHP 8.1.
• Dependencies: dropped the unused laminas/laminas-json and symfony/event-dispatcher; laminas/laminas-stdlib moved to dev dependencies (only the library's own dev config used it).
• Housekeeping since 7.6.0: CI restored on the 7.x branch, rector added and the code brought in line with rector 2.6.6, test namespace changed to Rollun\Test\, test environment fixes.
