feat(context): expose public API

[disrupted]

this would allow context toggles in keymaps and other user configs

I've been using this one in recent weeks and it's super convenient imo :)

keymap = {
    input_window = {
        ['<C-a>'] = {
            function()
                local enabled =
                    require('opencode.context').toggle_context('current_file')
                if enabled ~= nil then
                    vim.notify('current file context: ' .. (enabled and 'on' or 'off'))
                end
            end,
            desc = 'Toggle current file context',
            mode = { 'n', 'i' },
        }
    }
}

This is actually a pretty cool idea.

I will play around with it, but I really dig this

I would add the api tho the README.md and maybe a quick section about using it the way you described in the in ther repo.

maybe we could also add the toggle_context in the api file and configure it like so

'toggle_context#current_file' where anything after the # is the param ? But this coule be in another PR
