Pull Request Overview

This PR refactors the template and file handling logic while adding new subcommands for “template” and “for-each” along with an append option for merging list data. Key changes include:

• Removal of version management in internal/version.go (with version now managed in cmd/yutc/root.go).
• Significant refactoring in file and template loading functions across internal, cmd/yutc, and related files.
• Introduction of an append flag in internal/args.go and related modifications for handling list merges.

When BasicAuth is provided, the code still splits the bearerToken string instead of basicAuth. Consider replacing 'bearerToken' with 'basicAuth' in the SplitN call to correctly process basic authentication credentials.

Suggested change

	username := strings.SplitN(bearerToken, ":", 2)
	username := strings.SplitN(basicAuth, ":", 2)

[nitpick] Using panic here may abruptly crash the application in production. Consider returning an error from the Template() method or handling the error gracefully instead of panicking.

Suggested change

	func (t *YutcTemplate) Template() *template.Template {
	var err error
	// Make sure than any added templates have not overwritten the original template.
	t.template, err = t.template.Parse(t.templateString)
	if err != nil {
	panic(fmt.Errorf("this should have been caught during NewTemplate call: %w", err))
	}
	return t.template
	func (t *YutcTemplate) Template() (*template.Template, error) {
	var err error
	// Make sure than any added templates have not overwritten the original template.
	t.template, err = t.template.Parse(t.templateString)
	if err != nil {
	return nil, fmt.Errorf("this should have been caught during NewTemplate call: %w", err)
	}
	return t.template, nil
