refactor: rename request methods to remove send prefix (#161)

* 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.

* test: add tests for deprecated method aliases

- Update existing tests to use new method names (message, openLink)
- Add tests verifying deprecated aliases are same reference as new methods
- Add tests verifying deprecated aliases still work functionally

* refactor: rename message→sendMessage, resourceTeardown→teardownResource

- App.message() → App.sendMessage() (with deprecated message alias)
- AppBridge.resourceTeardown() → AppBridge.teardownResource() (with deprecated aliases)

This better follows the pattern where methods that send data have 'send' or action verb prefix.

* fix: update examples to use sendMessage instead of message

* fix: update basic-host to use teardownResource

* fix: update threejs-server to use sendMessage

* refactor: remove deprecated app.message alias

The app.message alias was removed since sendMessage is the correct name.
sendResourceTeardown already exists in AppBridge.

* refactor: remove resourceTeardown alias, keep only sendResourceTeardown
