Buzz for VS Code 0.8.8

First release on the VS Code Marketplace.

Install: VS Code Marketplace, or in VS Code: Extensions → search "Buzz for VS Code".
Demo: 1-minute video

An unofficial community extension for Buzz, Block's open-source team chat. It is not affiliated with or endorsed by Block.

• Chat in the editor: channels, threads and direct messages, live over the relay; mentions, search and a draft per thread.
• Agent work as a diff: proposals open in VS Code's diff view; reported branches and commits open in the changes editor, read from the agents' checkout without touching it.
• Buzz Lens: the conversations about the file you have open, on the lines they mention.
• Context in one step: send a selection, an error or terminal output to an agent, or a git diff to a channel.
• Jira: issue cards in the chat.

The extension works as in 0.8.7; this release adds the documentation, tests and CI. See the changelog.
