refactor: use loop to generate buffer navigation keymaps

[sazary]

Summary

Refactored repetitive buffer navigation keymap definitions into a clean loop, reducing code duplication from 9 individual keymap.set calls to a single loop.

Changes

• Replaced 9 repetitive keymap definitions with a for loop that generates keymaps 1-9
• Maintains identical functionality without any behavior changes
• Improves maintainability and makes the code more DRY

Why

• Reduces code repetition in keymaps configuration
• Makes it easier to maintain and extend buffer navigation keymaps in the future
• No functional changes, purely a code quality improvement

Pull request overview

Refactors Neovim buffer navigation keymaps to reduce repetition by generating <leader>1–<leader>9 mappings in a loop.

Changes:

• Replaced nine explicit vim.keymap.set calls with a for i = 1, 9 do ... end loop.
• Builds the lhs/rhs/desc strings dynamically based on i.

The generated desc uses .. i .. "th", which results in grammatically incorrect labels like "1th/2th/3th buffer". This also changes the user-visible keymap descriptions compared to the previous "1st/2nd/3rd" wording.

Consider generating the correct ordinal suffix (e.g., 1st, 2nd, 3rd, otherwise th) or using an explicit description table for 1–9 so the descriptions remain correct.

Suggested change

	for i = 1, 9 do
	vim.keymap.set("n", "<leader>" .. i, "<cmd>BufferLineGoToBuffer " .. i .. "<cr>", { desc = "Go to the " .. i .. "th buffer" })
	local buffer_ordinals = { "1st", "2nd", "3rd", "4th", "5th", "6th", "7th", "8th", "9th" }
	for i = 1, 9 do
	vim.keymap.set("n", "<leader>" .. i, "<cmd>BufferLineGoToBuffer " .. i .. "<cr>", { desc = "Go to the " .. buffer_ordinals[i] .. " buffer" })
