sing-box: Persist user data

[romeoahmed]

Improved the sing-box manifest with proper persistence and robust update logic.

• Persistence: Added config.json, cache.db, and config.d/ config/ folder to the persist field.

• Initialization: Added a pre_install script to:

  • Ensure $persist_dir exists (fixes directory missing errors in PowerShell).
  • Initialize config.json with UTF-8 (No BOM) and LF to prevent JSON parsing errors on the first run.
  • Touch an empty cache.db file.

• Update Logic: Optimized the checkver regex with a stable GitHub tag anchor.

• Notes: Added guidance for TUN mode administrator requirements and multi-config directory usage.

• Use conventional PR title: <manifest-name[@version]|chore>: <general summary of the pull request>

• I have read the Contributing Guide

It looks like it doesn't work. (: I'm not a Sing-box user.

"You can run with a directory of configs using: 'sing-box run -C $persist_dir\config.d'"

PS> sing-box check
FATAL[0000] read config at config.json: open config.json: The system cannot find the file specified.

PS> sing-box run
FATAL[0000] read config at config.json: open config.json: The system cannot find the file specified.

PS> sing-box run -C D:\Scoop\persist\sing-box\config.d
FATAL[0000] unmarshal merged config: EOF

What is the reason behind having both a config and a config.d folder, while keeping the config.json file outside of them?Is it sufficient to create only the config.d folder and place the config.json file within it?

These are just three common configuration methods for sing-box, and all three are retained here for compatibility. The error occurs because there are no configuration files in config.d/, while the outer config.json is an empty file to prevent sing-box from running directly without errors.
