fix(provider): trigger terminal redraw to fix empty columns on right side

[epheien]

Summary

• Fixed empty columns appearing on the right side of the terminal window
• Added autocmd to trigger terminal buffer redrawing when the cursor position is valid
• The fix listens for TermRequest events and redraws the terminal when cursor is ready

Changes

• Added TermRequest autocmd in Terminal:start() method
• The autocmd triggers a terminal redraw by switching to the terminal window and using feedkeys
• Autocmd is automatically deleted after triggering to avoid repeated redraws

{
  buf = 4,
  data = {
    cursor = { 1, 0 },
    sequence = "\27]11;?"
  },
  event = "TermRequest",
  file = "term://~/myconf//62305:opencode --port",
  id = 131,
  match = "term://~/myconf//62305:opencode --port"
}
{
  buf = 4,
  data = {
    cursor = { 1, 0 },
    sequence = "\27]66;w=1; "
  },
  event = "TermRequest",
  file = "term://~/myconf//62305:opencode --port",
  id = 131,
  match = "term://~/myconf//62305:opencode --port"
}
{
  buf = 4,
  data = {
    cursor = { 1, 0 },
    sequence = "\27]66;s=2; "
  },
  event = "TermRequest",
  file = "term://~/myconf//62305:opencode --port",
  id = 131,
  match = "term://~/myconf//62305:opencode --port"
}
{
  buf = 4,
  data = {
    cursor = { 1, 0 },
    sequence = "\27]4;0;?"
  },
  event = "TermRequest",
  file = "term://~/myconf//62305:opencode --port",
  id = 131,
  match = "term://~/myconf//62305:opencode --port"
}
{
  buf = 4,
  data = {
    cursor = { 25, 166 },
    sequence = "\27]12;#eeeeee"
  },
  event = "TermRequest",
  file = "term://~/myconf//62305:opencode --port",
  id = 131,
  match = "term://~/myconf//62305:opencode --port"
}

This is the event data of the TermRequest event when opencode -port is started.

Nice, thank you for this fix! That was bothering me but I didn't have time to investigate. I'm curious if there might be a deeper underlying issue causing this. But it's an isolated and reliable workaround, so definitely still an improvement 🙂
