Cleanup: plan files, repo bloat, writing de-slop

[jal-co]

• Sweep PLAN.md / roadmap / docs for completed or stale content (much of this session's work is done but plans predate it)
• Remove unused deps/registries (e.g. @bklit in components.json is unused)
• Writing pass over all site copy with the stop-slop skill
• Storybook QoL: tailwind recipe review, addon-highlight, play functions for interaction stories

Progress in PR #68:

• removed the unused custom shadcn registries from apps/web/components.json
• replaced the private Hugeicons Pro package with the equivalent free Hugeicons icon, removing the private npm token/install dependency from CI and local setup docs
• added deterministic Fumadocs source generation before CI typecheck

Remaining: plan/roadmap sweep, broader copy pass, and Storybook interaction/QoL work.

Audit update: unused registries and major docs/design cleanup landed in #68/#70. Keep open for the remaining plan/roadmap reconciliation, dependency audit, final copy pass, and Storybook interaction/QoL work.
