chore: remove cspell

[DylanPiercey]

Removes the cspell spell checker from the repo. Deletes cspell.json, drops cspell from the root lint script and devDependencies, and removes the inline cspell:disable-next-line / cspell:ignore directives that only existed to satisfy it. AGENTS.md and agent-feedback/README.md are updated to describe what pnpm run lint actually runs now.
