Fix ENOSPC error from chokidar monitoring node_modules

[Copilot]

Chokidar was monitoring the deps directory including node_modules symlinks, exhausting inotify watchers (~8243 files in node_modules vs 8192 limit) and causing ENOSPC errors with 100% CPU from retry loops.

Changes

• Add node_modules and .git to chokidar ignored patterns in back/loaders/deps.ts
• Use properly anchored regex patterns to avoid false positives (e.g., my_node_modules_backup.txt still watched)

const watcher = chokidar.watch(source, {
  ignored: [
    /(^|[\/\\])\../, // ignore dotfiles
    /(^|[\/\\])node_modules([\/\\]|$)/, // ignore node_modules
    /(^|[\/\\])\.git([\/\\]|$)/, // ignore .git
  ],
  persistent: true,
});

Patterns match only actual directories at any path depth, consistent with existing dotfiles pattern.

<issue_description>### Qinglong version

青龙 2.20 debian 版本

Steps to reproduce

青龙 2.20 debian 版本启动后 CPU 持续占用 100%+，错误日志显示 inotify watcher 数量超限。

What is expected?

环境信息

• 青龙版本：2.20.0-1
• 镜像：whyour/qinglong:debian
• 系统：Ubuntu 22.04
• Docker 版本：24.x

What is actually happening?

Error: ENOSPC: System limit for number of file watchers reached, watch '/ql' code: 'ENOSPC', syscall: 'watch', path: '/ql'

System Info

Any additional comments?

原因分析

容器内文件统计：

• /ql 总文件数：约 9258 个
• /ql/node_modules 文件数：约 8243 个
• Linux 默认 inotify 限制：8192 个

chokidar 监听了整个 /ql 目录，包括 node_modules，导致 watcher 数量超限后疯狂重试，CPU 飙高。

建议修复

在 chokidar 配置中忽略 node_modules：

chokidar.watch('/ql', {
  ignored: ['**/node_modules/**', '**/.git/**']
})


echo 16384 | sudo tee /proc/sys/fs/inotify/max_user_watches
