chore(build): Migrate cspell to hve-core modular dictionary structure

[WilliamBerryiii]

Mindfully merge hve-core's modular cspell dictionary structure while preserving project-specific settings and removing dictionaries irrelevant to this Python/Terraform/Bash codebase.

Changes

• Add .cspell/ directory with 4 dictionary files from hve-core
• Update .cspell.json (merge, not replace) with:
  • Add relevant dicts: k8s, docker, terraform, data-science
  • Remove irrelevant dicts: typescript, node, php, go, html, css, cpp, csharp, latex, npm
  • Add 4 custom dictionary definitions
  • Add terraform ignore paths
• Migrate 13 project-specific words to general-technical.txt
• Remove obsolete .cspell-dictionary.txt
