fix(mcp): normalize streamable http server aliases

@@ -381,6 +381,7 @@ Notes:
 - `list` sorts server names.
 - `show` without a name prints the full configured MCP server object.
 - `set` expects one JSON object value on the command line.
+- Use `transport: "streamable-http"` for Streamable HTTP MCP servers. `openclaw mcp set` also normalizes CLI-native `type: "http"` to the same canonical config shape for compatibility.
 - `unset` fails if the named server does not exist.

+OpenClaw config uses `transport: "streamable-http"` as the canonical spelling. CLI-native MCP `type: "http"` values are accepted when saved through `openclaw mcp set` and repaired by `openclaw doctor --fix` in existing config, but `transport` is what embedded Pi consumes directly.
