docs(skills): fix broken related_skills references (#37338)

Salvaged from PR #38820 by @bedirhancode, re-applied at current skill
locations (obliteratus and s6 moved to optional-skills/ since the PR):

- research-paper-writing: drop ml-paper-writing (never existed)
- touchdesigner-mcp: drop native-mcp (consolidated) + hermes-video (never existed)
- obliteratus: vllm -> serving-llms-vllm, gguf -> llama-cpp
- s6-container-supervision: drop hermes-agent-dev (not a repo skill)

4 of the original 8 hunks were dropped: heartmula already fixed in
#70453; native-mcp SKILL.md deleted from main; architecture-diagram and
comfyui hunks removed refs to concept-diagrams and
stable-diffusion-image-generation, which are valid optional skills.
