fix: only call denops#plugin#wait after denops#plugin#load

[Copilot]

When a lazy plugin with a denops component is triggered (e.g. via on_event = 'InsertEnter') before denops finishes its async startup, denops#plugin#wait was executing unconditionally whenever the server wasn't 'stopped' — even though denops#plugin#load had been skipped (requires 'running'). Since plugin.sourced is set to true before the denops section, the plugin gets permanently marked as sourced with its denops component never actually loaded.

Change

Move denops#plugin#wait inside the denops#server#status() ==# 'running' block so it only fires when denops#plugin#load was actually called:

" Before
if denops#server#status() ==# 'running'
  call denops#plugin#load(name, ...)
endif
if denops#server#status() !=# 'stopped'   " true when 'starting' too
      \ && plugin->get('denops_wait', v:true)
  call denops#plugin#wait(name)            " called on never-loaded plugin
  redraw
endif

" After
if denops#server#status() ==# 'running'
  call denops#plugin#load(name, ...)
  if plugin->get('denops_wait', v:true)
    call denops#plugin#wait(name)
    redraw
  endif
endif
