[eric] browser: composer finder pierces shadow DOM (Reddit shreddit, Telegram, WhatsApp, Slack build their composer inside web-component shadow roots a light-DOM querySelectorAll can't see); bounded recursive walk (depth 8, 400-node cap). Live finder-probe on real DOMs: correctly picks X's contenteditable 'Post text' + excludes the search combobox; the remaining wall is that lazy/dialog/chat-gated composers aren't rendered at scan time (detection is downstream of render)
