Android: press @ref fails with "press requires x y" error #139

Description

press @ref fails on Android emulator with Error (INVALID_ARGS): press requires x y, even though the ref was obtained from a successful snapshot -i call.

Steps to Reproduce

1. Start an Android emulator session:

   agent-device open com.example.app --platform android --session my-session

2. Take a snapshot:

   agent-device snapshot -i --session my-session

   Output includes refs like @e11 [text] "My App".

3. Try to press the ref:

   agent-device press @e11 --session my-session

4. Error:

   Error (INVALID_ARGS): press requires x y
   

Expected Behavior

press @e11 should tap the element identified by the ref, as documented in the SKILL.md:

press is canonical tap command; click is an equivalent alias.

The example agent-device press @e2 suggests refs should work with press.

Workaround

Using find "text" click works correctly:

agent-device find "My App" click --session my-session

Environment

• agent-device version: latest (installed via npx)
• Platform: Android emulator (Pixel 8 Pro API 36)
• Host OS: macOS (Darwin, Apple Silicon)
• Node: v22+

Notes

PR #70 unified press and click to support @ref, coordinate, and selector targets. This may be a regression or incomplete implementation for the Android platform.
