Refactors the NormalSub feature to move away from a hardcoded `/sub/normal/` path and a restrictive single-word subpath. This change introduces support for multi-segment, slash-separated subpaths (e.g., `path/to/resource`), providing greater flexibility for creating descriptive and structured subscription URLs.
- Add service status validation before editing subpath
- Use systemctl reload for Caddy config changes
- Add fallback to restart if reload fails
- Enhance user feedback with old/new subpath comparison
- Improve error handling and status verification
This commit introduces a new 'edit_subpath' command to the
normalsub.sh script. This allows users to change the SUBPATH
variable in the .env file and automatically restarts the
hysteria-normal-sub service to apply the changes.
