Add mini.starter dashboard and optimize lazy loading

- Add startup time tracking with hrtime in init.lua
- Configure mini.starter with Neovim ASCII logo and plugin stats
- Switch mini.notify to load on first vim.notify call
- Switch mini.cmdline to load on first ':' keypress
- Add mini.icons eager loading
- Remove x-mode 'p' keymap (handled by mini.operators)
