feature: allow interrupt opencode / Claude

[louwers]

Did you check the docs?

• I have read all the sidekick.nvim docs

Is your feature request related to a problem? Please describe.

The key to interrupt is 'escape' which switches from insert mode to normal mode instead.

Describe the solution you'd like

I'd like the escape key not to be hijacked.

Ctrl-[ can be used to switch to normal mode instead.

Describe alternatives you've considered

Adding some alternative keybind to opencode for interrupt. However escape is the most natural.

Plus one on this.
It also help with other CLIs, like Claude Code.

My workaround to make this working is:

  opts = {
    cli = {
      win = {
        keys = {
          escape = { "<Esc>", "<c-[>", mode = "t" },
        },
      },
    },
  },
