v2.0.4

What's Changed

Chat: replaced tmux polling with direct Gateway API SSE streaming — the Chat page no longer spawns a tmux agent session and polls for output. Instead, it streams directly via /v1/chat/completions (OpenAI-compatible SSE endpoint).

Benefits

• Instant response — no 2-second polling delay, no agent spawn overhead
• True abort — AbortController kills the fetch, not just stops showing output
• Session continuity — X-Hermes-Session-Id header maintains conversation context
• Cleaner state — no agent lifecycle management

Added

• api.streamChat() — async generator yielding SSE delta tokens from /v1/chat/completions
• DnaLoader component — animated DNA helix loading indicator
• Architecture diagram — docs/miniapp-v2-architecture.html — full system diagram

Removed

• tmux agent spawn/poll/cleanup from ChatPage (Agents page still has power-user tmux spawning)
