- Move ollama plugin out of user.lua, as that file has basically just UI
configuration
- Remove zen astrocommunity configuration and enable snacks.nvim's zen
- Disable telescope integration from quickgd.nvim since we use
snacks.nvim's picker
- Remove unused community plugins
- Configure catppuccin/nvim's integrations, adding snacks.nvim and
blink.cmp while removing notify, telescope and nvim-cmp
