Description

This PR fixes an issue where oil.nvim throws an error (E565: Not allowed to change text or change window) when Neovim is started with a directory argument (e.g., nvim .).

The error occurs because during initialization, the plugin attempts to delete buffers in a context where Neovim doesn't allow buffer modifications. This fix wraps the buffer deletion operations in pcall() to safely handle these restrictions.

Steps to reproduce

1. Lua config:

        config = function()
            require("oil").setup()

            vim.keymap.set("n", "<leader>e", function()
                require("oil").open()
            end, { desc = "Open Oil file explorer" })
        end

2. Navigate to any directory in your terminal
3. Run nvim .
4. Hit <leader>e
5. Observe the error message in oil's loading process

Changes

• Added pcall() around buffer deletion operations in rename_buffer function
  • This allows the function to continue execution even when buffer deletion fails and ensures oil opens the correct directory
