chore(anthropic): raise SDK floor for native effort fields

Require Anthropic 0.100.0 so adaptive thinking, disabled thinking, and all advertised effort values use typed SDK parameters instead of extra_body compatibility.

 ## Gateway
 
 `nanobot gateway` starts enabled chat channels, WebUI/WebSocket when configured, cron-backed system jobs, Dream, heartbeat, and the health endpoint. Most local browser users should start with `nanobot webui`; use `gateway` directly for service management, chat app operation, and advanced deployment. By default it runs in the foreground, which keeps existing scripts and terminal workflows unchanged. Use `--background` when you want a local macOS, Linux, or Windows process that you can manage from the CLI.

-### Cloudflare Tunnel + Cloudflare Access
-
-For a local `cloudflared` process in front of nanobot, Cloudflare Access can
-authenticate the user before forwarding the request and add
-`Cf-Access-Jwt-Assertion`. Opt in to trusted-proxy no-token mode only when the
-direct TCP peer is the tunnel process and the assertion is non-empty:
-
-```json
-{
-  "gateway": { "host": "127.0.0.1" },
-  "channels": {
-    "websocket": {
-      "host": "127.0.0.1",
-      "port": 8765,
-      "publicWsUrl": "wss://nanobot.example.com/",
-      "trustedProxyAuth": {
-        "trustedPeerCidrs": ["127.0.0.1/32", "::1/128"],
-        "assertionHeader": "Cf-Access-Jwt-Assertion"
-      }
-    }
-  }
-}
-```
-
-This is two-part authorization: a trusted direct loopback peer **and** a
-non-empty Cloudflare Access assertion. A trusted CIDR alone is not a bypass.
-For this flow `/webui/bootstrap` returns connection metadata without a
-bootstrap token or REST API token; the proxy assertion authorizes the WebSocket
-handshake and REST requests directly.
-
-Set `publicWsUrl` to the browser-facing `wss://` endpoint when the tunnel sends
-the origin host header (such as `127.0.0.1:8765`); otherwise the WebUI could
-attempt to open its WebSocket directly against the loopback address.
-The assertion header must be generated
-by Cloudflare Access after authentication; routing/client metadata headers such
-as `Host`, `Forwarded`, `X-Forwarded-*`, `X-Real-IP`, and `CF-Connecting-IP`
-are rejected as `assertionHeader` values. Nanobot trusts the assertion but does
-not cryptographically validate the JWT, so configure the tunnel and Access
-policy carefully and do not expose the nanobot listener directly to untrusted
-clients. Forwarded client headers do not establish proxy trust.

-The embedded WebUI's `/webui/bootstrap` route returns a WebSocket token and

-`trustedProxyAuth` authenticates the direct proxy peer, it returns connection
-metadata only: no bootstrap token, no REST API token, and no token query

-
-### Trusted proxy no-token bootstrap
-
-`trustedProxyAuth` is an opt-in alternative for deployments where an
-identity-aware reverse proxy authenticates the user before connecting to nanobot.
-The proxy assertion becomes the authentication boundary for the entire WebUI
-surface: `/webui/bootstrap`, the WebSocket handshake, and REST API routes.
-Bootstrap is accepted only when **both** the direct TCP peer matches one of
-`trustedPeerCidrs` and the configured assertion header is present and non-empty.
-A trusted address by itself is never sufficient.
-
-Nanobot deliberately uses only `connection.remote_address` for the peer check.
-It never uses `X-Forwarded-For`, `Forwarded`, `X-Real-IP`, `CF-Connecting-IP`,
-or `X-Forwarded-Host` to decide whether the proxy is trusted. Nanobot trusts the
-assertion supplied by the explicitly trusted peer, but does not cryptographically
-validate or interpret the JWT/assertion contents. Do not enable this option if
-untrusted clients can connect directly to the nanobot listener.
-
-The configured assertion header must be a proxy-generated authentication
-assertion, not a routing or client metadata header. Headers such as `Host`,
-`Forwarded`, `X-Forwarded-*`, `X-Real-IP`, and `CF-Connecting-IP` are rejected
-by configuration; use the identity provider's post-authentication assertion
-header instead (for example, `Cf-Access-Jwt-Assertion`).
-
-For example, a local Cloudflare Tunnel with Cloudflare Access can validate the
-user at the edge and forward the resulting `Cf-Access-Jwt-Assertion`:
-
-```json
-{
-  "channels": {
-    "websocket": {
-      "host": "127.0.0.1",

-      }
-    }
-  }
-}
-```
-
-This works only when the directly connected `cloudflared` process reaches
-nanobot over the configured loopback address and supplies a non-empty assertion.
-Keep nanobot firewalled from untrusted clients; this configuration is not a
-CIDR-based bootstrap bypass.
+The embedded WebUI's `/webui/bootstrap` route also returns a WebSocket token.

-The command safely prepares the local WebSocket channel, starts both the gateway and Vite,
-and opens `http://127.0.0.1:5173`. Vite proxies to the configured WebSocket channel and applies
-frontend changes with HMR. Press Ctrl+C in that terminal to stop both processes.
-
-Use `--no-open` to skip opening a browser. `--dev` is foreground-only and cannot be combined
-with `--background`.
