Conversation
Adds a small shortcut system around a single document-level keydown listener plus a help modal. Mirrors the bindings claude.ai/chat exposes, skipping ones that don't map (artifacts, force-send, settings). Global: ⌘⇧O new chat, ⌘K focus search, ⌘/ shortcuts modal, Esc cascades to modal → search → stop generation. Chat: ⌘⇧S sidebar, ⌘⇧; focus input, ⌘⇧C copy last response, ⌘⇧⌫ delete current (confirmed), ⌘\ side panel (already existed). Mac/Linux labels and Backspace/Delete aliases render automatically.

Summary
Adds a small keyboard-shortcut system to the web UI plus a help modal, mirroring the bindings that claude.ai exposes. Skips ones that don't map to Nerve (artifacts, force-send, settings).
