v0.12.4

Fixed

• ScrapeItemJob failing with "Locking a record with unpersisted changes" on Rails 8.1.2 — replaced assign_attributes with reload in scraping state machine
• FetchFeedJob permanently failing on advisory lock contention — switched to exponential backoff with jitter and graceful discard on exhaustion
• OPML import dismissal only hiding the latest notification — now dismisses all undismissed import histories for the user
• Dashboard pagination not working — schedule group keys were silently dropped by overly restrictive param whitelist regex
• Source filter dropdowns not auto-submitting — missing filter-submit Stimulus controller declaration on search forms (also fixed on logs index)
