* docs(agents): add haskell-pro
* fixup
* Move haskell-pro agent to functional-programming plugin
- Moved plugins/haskell-development/agents/haskell-pro.md to plugins/functional-programming/agents/haskell-pro.md
- Updated path reference in docs/agents.md
This addresses review feedback to place the Haskell agent in the existing functional-programming plugin alongside elixir-pro, rather than creating a new haskell-development plugin.
