Ensure template is recompiled when template file changes

Pull request overview

This PR refactors the template reload mechanism to ensure automatic recompilation when template files change. Previously, templates were pre-parsed into tokens at macro expansion time, which meant changes to template files wouldn't trigger recompilation. The new approach stores the original template string using include_str!() for file-based templates, creating a compile-time dependency that Cargo tracks for automatic recompilation.

Key changes:

• Replaced TOKENS constant with TEMPLATE constant storing the original template string
• Split Parse error into ParseNew and ParseOld for clearer error messages
• Template parsing now happens at runtime in the reload() method instead of at compile time
