Add support for detecting and tracking image-only spam across channels. spamDetector.js: introduce image helpers (isImageAttachment, getImageAttachments), buildImageFingerprint, isImageOnlyMessage, and extend detectSpam to report image-only reasons and a duplicateImageAcrossChannels flag. rapidSpamTracker.js: refactor cross-channel tracking with trackCrossChannelPost, pruneExpiredPosts, dedupePriorMessages, and add trackImageOnlySpam which uses optional image fingerprints; export dedupePriorMessages. index.js: wire image-only tracking into message handling (build fingerprint, trackImageOnlySpam, pass duplicateImageAcrossChannels to detectSpam), merge and dedupe prior message lists, and include attachments in mod log previews. commands.js: update detection rules text to mention image spam. These changes enable identifying image-only spam (including fingerprinting) and avoid duplicate prior-message entries when creating moderation logs.
