Changes:

• Added a webserver to the examples/server directory along with a README.md file for documentation.

• Fixed a bug in the txt2img module related to the sample_strength parameter.

• Corrected some typos in the VideoResnetBlock class.

• Addressed a potential bug in the following line of code:

  gglm_ctx_local->engine_meta.env_sigma_scheduler.assign(sigmas.begin() + sample_steps - t_enc - 1, sigmas.end());
  

  If sample_steps is equal to t_enc, the line would effectively become:

  gglm_ctx_local->engine_meta.env_sigma_scheduler.assign(sigmas.begin() - 1, sigmas.end());
  

  which could lead to undefined behavior. The bug has been fixed to handle this edge case properly.
