As discussed in https://github.com/yetone/avante.nvim/pull/2536 the
project should either use luv bindings from luals or luvit-meta
library, but not both, as they conflict with each other (especially
with uv.uv_timer_t). Given that other projects such as kickstart.nvim
and lazydev.nvim are switching to use the former, we should do the same
and drop luvit-meta dependency.
Also adjust code that was using luvit-meta's annotations for timers.
