OpenCode Workbench 0.2.0

Major VS Code experience update.

Added

• Copilot-style chat in the VS Code Secondary Side Bar.
• Session switching from the chat header and an expandable native Sessions work queue.
• Top-right editor action for opening chat.
• Ctrl+Alt+N keybinding for creating a new OpenCode session.
• Visual Studio Marketplace publication under nulifyer.opencode-workbench.

Changed

• Redesigned messages, reasoning, tool activity, empty state, composer, model controls, status, and accessibility while preserving existing Workbench features.
• Raised minimum VS Code version to 1.106 for stable Secondary Side Bar placement.
• Expanded Linux, macOS, and Windows installation and usage documentation.

Migration

• Pre-Marketplace builds used extension ID opencode-workbench.opencode-workbench-vscode. Verified installers migrate to nulifyer.opencode-workbench.
• Run OpenCode: Set Server Password again only if the password was stored exclusively in the legacy extension Secret Storage. Unix server.env installations retain credentials.

Security

• GitHub build provenance and SHA-256 manifests cover every release asset. The Marketplace publishes the same verified VSIX.

Requires OpenCode 1.18.8 or newer within major version 1, and VS Code 1.106 or newer.
