Spam Blocker

Spam Blocker — 1.0.2

• Large reduction in chat-processing cost. The similarity check ran a full Levenshtein matrix against every recent message from a sender; it now skips comparisons that can't reach the threshold on length alone (edit distance is at least the length difference, so this changes no decisions — only skips work that was guaranteed to fail).
• Fixed unbounded memory growth: message history and auto-ignore counters were only pruned for whoever just spoke, so everyone who said one thing in trade chat stayed in memory for the rest of the session. Stale senders are now swept.
• Replaced the placeholder Author: You.
• ## Category → ## Category-enUS (the client reads the locale-suffixed key, so it was landing in "Other").
