MBrain 0.3.0 adds 16 structured tools so MCP clients can operate Android UI and diagnose applications without constructing shell commands for each task.

• Phone control: node trees, selector/coordinate click and long press, Unicode text input, swipes, navigation, waits, and text clipboard operations through a fixed app_process helper.
• Diagnostics: bounded logs, AppOps get/set with readback, process and resource reports, network state, and DNS/TCP probes. Tools register under the enabled Root/Shizuku source.
• Use the fixed development package com.powercess.mbrain.dev and launcher name MBrain 开发版; release remains com.powercess.mbrain. Update test scripts and development docs to stop using temporary capability-test package names.
• Prepare version 0.3.0 (code 5) and release notes. No release tag is created by this PR.

Validation:

• Debug, AndroidTest, and Release APK builds; 140 JVM tests and 14 script tests passed.
• Debug/Release lint: 0 errors (33/26 warnings); both APKs passed four-ABI checks.
• Connected Android 15 device: all capability smoke checks and authenticated Shizuku/MCP integration passed with the fixed development package. Clipboard restoration and credentials remain device-local.
• Staged-source scan: no findings. Other Android versions, OEMs, and direct Root execution have not been validated.
