refactor: rename request methods to remove send prefix

Following the MCP TS SDK convention where request methods don't have
the "send" prefix (reserved for notifications):

- App.sendMessage() → App.message()
- App.sendOpenLink() → App.openLink()
- AppBridge.sendResourceTeardown() → AppBridge.resourceTeardown()

The old method names are kept as deprecated aliases for backwards
compatibility.

Updated all examples to use the new method names.
