GetTextAroundCursorTool
Reads the text surrounding the cursor via InputConnection.getTextBeforeCursor / getTextAfterCursor. Requires the droid-mcp IME to be active with an editor focused, else imeNotActiveError. Password fields (TYPE_TEXT_VARIATION_PASSWORD) and FLAG_SECURE windows are not delivered plaintext by the platform, so those return empty/masked content. Output: before and after strings (empty if the editor has no more text in that direction).
