- Synchronized the installation guidance in the English and Chinese README documents.
- Removed the separate `install-server.sh` script content display, as it has been integrated into the new `install.sh` script.
- Added panel printing functions (print_panel, print_subheader) to install-server.sh and install.sh,
for improved interface display.
- Introduced the ensure_command_access function to automatically link the drip command to system paths (e.g., /usr/local/bin),

- Unified multilingual prompts and optimized user experience.
The original method of storing multilingual messages using associative arrays was replaced with the functions `msg_en` and `msg_zh`,
to provide better shell compatibility. The `prompt_input` function was also introduced to unify user input logic,
improving stability and maintainability across different shell environments.
Added the `--short` flag to the `version` command for printing version information without styles.
In this mode, only the version, Git commit hash, and build time in plain text format will be output, facilitating script parsing.
Optimized Windows process detection logic to improve runtime accuracy.
