Release 4.206.0

The menu keeps a stream playing, the Feed in the menu is searchable with the one composer at its top, and a Code task opens in the Dock's step card.

• The menu no longer pauses what is playing (#461, ask 360). Opening the menu on a phone left live video and audio paused under it; the sheet now leaves media alone and the page can read the player's state.
• The Feed in the menu (#463, ask 360). Feed search uses Community's search and examples through Network, with loaded-card filtering when search is unavailable; the example searches are chips that fill the field. The Feed's post form is the one composer (OpenVibeComposer: files, paste, drop, commands, drafts, settings); each picture needs a description and other files upload to Media. Its + and the example chips carry their own styles in the menu (they drew as bare browser buttons in the PR's screenshots).
• Chat and Vibe (#463). The Chat summary's Vibe row is an accessible Open Vibe button that selects the menu's Vibe tab; on a desktop Chat and Vibe open the Dock after the menu closes, and the Dock opens from its pill only when that pill is visible.
• A Code task in the Dock (#465, ask 354). The Dock's Code card shows the task's live steps with the AG-UI step view (agent-session.js card mode) and opens the whole run.
