Produce verifiable visual/behavioral proof-of-work for changes to this VS Code extension. Use when making UI or user-visible changes, when the user asks to "show what it looks like", when producing PR demo content, or when completing a task that has observable output. Captures either Svelte component visuals via the Vite fixture server + agent-browser (fast, no VS Code) or end-to-end extension behavior via CDP-driven real VS Code (slow, full fidelity). Assembles output into a showboat markdown doc with embedded screenshots and verifiable command output. Trigger when the user invokes `/visual-proof`, asks for screenshots, wants before/after comparison, or finishes a feature with visible behavior.
