v0.6.0 — Rolling trending ticker bar

📈 Rolling ticker bar (CNBC/Bloomberg style)

A live TRENDING strip under the chat header that scrolls right→left, showing what the chat is talking about right now — pulled live from the messages, no setup.

• Three kinds of chips — trending stock/crypto tickers, @mentioned people, and topic keywords (1–2 words each).
• Click a chip → instant chat search (tickers search the bare symbol, people @name, topics the word).
• Live prices on ticker chips (green ▲ / red ▼ % change), pulled from Yahoo Finance via the background service worker — no API key, no CORS. Crypto maps to <SYM>-USD. Unpriceable symbols just show the symbol.
• Hover eases the strip to a halt so the chip under your cursor is clickable; leave and it glides back to speed. Respects prefers-reduced-motion.
• Selection — looks at the last 2 hours of chat, frequency-scored with newer mentions weighted higher (recent leads, but a heavily-discussed earlier mover still surfaces). Tickers via $SYMBOL (known or unknown) or bare ALL-CAPS from the built-in list; $MSFT/MSFT deduped. Topics gated to ≥2 distinct authors + stopword/length filter so filler doesn't leak. Tickers rank first, then people, then topics.

New https://query1/query2.finance.yahoo.com/* host permissions (price fetch). New pure lib/trending.js with 18 unit tests; full suite 462 green. Independent design + code review both ran.

Install/upgrade: reload the unpacked extension at chrome://extensions and accept the new Yahoo host permission.
