fix: Watcher not updating on file change

[ALameLlama]

Currently the watcher doesn't always update the git status without reopening fyler, I mostly noticed this when editing files or adding new files.

Before:
Screencast_20260704_133548.webm

After:
Screencast_20260704_133913.webm

Replace final schedule call with following:

vim.schedule(function()
  if not watch_state[buf_id] then return end
  if vim.bo[buf_id].modified then return end

  local pending = state.pending_refresh
  state.pending_refresh = nil

  pcall(function() instance:refresh(pending) end)
end)

Because I want it return before setting pending refresh to nil.

Sounds good, I'll update this on the weekend and test it out

Can you hold off on merging this? I've noticed I'm getting a weird flashing only on hidden files. I'll need to look into what is causing this

I think the CI is just failing again due to performance?

Sorry for the delay on this but the issue seemed to be since both shared a namespace it would updated and clear it causing a flashing issue, adding cache and a separate namespace.

if you have a better way to handle this I'm all ears :)

Sure tell you when I got free

[ALameLlama]

take your time, I'll keep playing around with it and update you if I notice anything else weird
