bug: gitbrowse prepends a second scheme to `http://` remotes

Did you check docs and existing issues?

• I have read all the snacks.nvim docs
• I have updated the plugin to the latest version before submitting this issue
• I have searched the existing issues of snacks.nvim

Neovim version (nvim -v)

Operating system/version

Describe the bug

For a repository whose remote uses plain http:// (e.g.: self-hosted GitLab instances on an internal network), Snacks.gitbrowse() opens an invalid URL with two schemes glued together:

remote: http://git.example.com/group/subgroup/repo.git
opened: https://http://git.example.com/group/subgroup/repo

The cause is in M.get_repo() (lua/snacks/gitbrowse.lua:96):

return ret:find("https://") == 1 and ret or ("https://%s"):format(ret)

Although the remote_patterns loop handles http correctly with { "^(https?://.*)%.git$", "%1" }, the final scheme check only recognizes https://. Therefore, an http URL that already has a scheme is treated as schemeless and gets https:// prepended.

No error is shown; the notification and the browser both receive the malformed URL.

Steps To Reproduce

1. Create a repo with a plain-http remote:

mkdir /tmp/gitbrowse-http && cd /tmp/gitbrowse-http
git init -q .
printf 'line1\nline2\nline3\n' > README.md
git add README.md && git commit -qm init
git remote add origin http://git.example.com/group/subgroup/repo.git

2. Open the file: nvim README.md
3. Type <leader>gY and then paste.
4. The printed URL is https://http://git.example.com/group/subgroup/repo

Expected Behavior

In the example above, I expect to see http://git.example.com/group/subgroup/repo

Repro

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
  spec = {
    { "folke/snacks.nvim", opts = {} },
    -- add any other plugins here
  },
})

Workaround while #2955 is not merged:

I've put this in my lua/plugins/extended-snacks.lua:

return {
  "folke/snacks.nvim",
  -- TODO: remove when https://github.com/folke/snacks.nvim/pull/2955 is merged
  init = function()
    vim.api.nvim_create_autocmd("User", {
      -- trying to make sure this patch runs after snacks has loaded
      pattern = "VeryLazy",
      once = true,
      callback = function()
        local gitbrowse = require("snacks.gitbrowse")
        local get_repo = gitbrowse.get_repo
        gitbrowse.get_repo = function(...)
          return (get_repo(...):gsub("^https://(https?://)", "%1"))
        end
      end,
    })
  end,
  -- rest of configs (if any)...
}
