Refactor lazy loading: unify treesitter/LSP deferral via lazy.on_event

- Move VimEnter autocmd from init.lua to pack.lua using lazy.on_event
- Convert treesitter.lua to modular M.setup() pattern
- Simplify lsp.lua: remove redundant comment, inline diagnostic config
- Reorganize pack.lua: group finders, add fugitive keymaps, adjust header indent
