docs: reorder Installation before agent-design section and rewrite the duality framing

- Rename `## Install` to `## Installation` and move it ahead of the agent-design section so practical setup comes first
- Replace generic "Built for agents" block with "Manual setup, agent execution" — frames the CLI as two distinct surfaces (manual wallet ops with passphrase prompts and QR sync vs JSON-first analysis/trading meant for agents) so it doesn't read as Alpaca's framing rerun
- Tie agent-token + policy story to the duality: stage by hand once, then hand a scoped token to automation

-### Built for agents
-
-This CLI is designed primarily for AI agents and automation pipelines, not as a general-purpose interactive terminal tool. JSON-first output by default, no confirmation prompts on data commands, structured error codes on stderr. Every command executes immediately and returns parsable output.
-
-**This means destructive commands are truly destructive.** Once an agent token is configured, `zerion swap` and `zerion bridge` execute trades immediately — no "are you sure?" dialog. Treat agent tokens like API keys with spending power and use [agent policies](#agent-policies) to scope what they can do.

+## Manual setup, agent execution
+
+Zerion CLI splits into two surfaces, by design.
+
+- **Wallet management is manual.** `wallet create`, `import`, `backup`, and `delete` all prompt for a passphrase. `wallet sync` emits a QR code you scan with the Zerion app. These commands assume a human at the keyboard — no key material moves without an explicit gesture.
+- **Analysis and trading are for agents.** `analyze`, `portfolio`, `swap`, `bridge`, and `send` emit JSON to stdout, structured errors to stderr, and skip confirmation dialogs. Once an agent token is configured, trades fire immediately.
+
+The split is the point. You stage a wallet by hand once — create or import a key, set a passphrase, mint an agent token, attach a policy — then hand the agent token to an automation that can only do what the policy allows. Treat agent tokens like API keys with spending power; use [agent policies](#agent-policies) to scope them down to specific chains, addresses, or expiry windows.

 ## Authentication
 
 Three options. The CLI auto-detects which is active.
