feat(vscode): add Daemon debug configuration
Add a new debug configuration for Daemon mode in VS Code launch settings
to facilitate debugging with specific environment variables and flags.
fix(config): use filepath.Dir for config path resolution
Change from assigning raw config path to using filepath.Dir to get the
directory of the config file, ensuring proper directory handling.
refactor(filehandler): improve file access security and directory handling
Improve security checks by using Lstat instead of Mode check for symlinks,
enhance directory handling when URL ends with "/" to prevent path traversal
errors, and refine path resolution logic to properly handle root directory
cases.
fix(config): disable SSL and update example root path
Disable SSL for teststatic server configuration and update root path
from relative "./example" to "../example" for proper example directory access.
