Research direction
Start by tracing how Java completion candidates and constructor argument snippets are provided or configured in Lithe, then check the editor and Java language support entry points. The issue gives no file names or reproduction details, so first confirm the behavior on Windows with the reported new No example. Done when accepting Node can insert new Node() with the cursor inside, while any existing argument snippet behavior can be retained through a setting.

Description
Problem to solve / 要解决的问题
Java 编辑场景中，输入 No 并通过默认 Tab 补全 Node 构造调用后，会得到 Node(key, value) 一类包含参数名的调用。用户希望自行输入实际参数，自动插入的 key、value 增加了删除和替换操作。用户截图显示 private final Node head = new Node(key, value);，参数名下出现诊断波浪线。
Proposed solution / 建议方案
提供仅补全构造器名称和括号的行为，例如在 new No 处接受 Node 候选后得到 new Node()，光标位于括号内，由用户输入实参。不要自动填入 key、value，也不要求自动猜测或填入 0、0。可以提供明确的补全设置，使需要参数 snippet 的用户仍可保留该行为。

P2 / 后续考虑：目前不着急，可安排到后续版本
Alternatives considered / 已考虑的替代方案
当前可以手动删除补全生成的参数名，再输入实参，但重复编辑时不便。仅用可替换的参数名占位不符合本用户希望默认留空的操作习惯。
Additional context / 补充信息
平台：Windows。用户于 2026-10-23 表示使用最新 Lithe，具体版本号及 Java 插件/JDT LS/JDK 版本未提供。此项作为补全行为的改进建议，未宣称已证明语言服务器或 snippet 实现故障；Agent 未运行复现。
原始示例中 0、0 是用户手动输入的实参目标，不是要求系统自动生成的默认值。截图未上传，以上文字保留相关最小代码。
建议标签：platform:windows、area:language、area:editor、P2。
