Add lualine as statusline, winbar, and bufferline replacement

[uloco]

Migrates the old lualine config to the new lazy.nvim setup and configures
it to replace three separate components:

• Statusline: mode, branch, filename, diagnostics, encoding, filetype
• Tabline: buffer list with index numbers + tab indicator
• Winbar: relative file path per window (replaces vim.opt.winbar)

Also updates laststatus to 3 for globalstatus compatibility.

Pull request overview

This PR migrates the lualine configuration from the old packer-based Neovim setup to the new lazy.nvim-based setup. It configures lualine to handle three UI components: statusline (showing mode, branch, filename, diagnostics, encoding, and filetype), tabline (displaying grapple-tagged files and tabs with custom labels), and winbar (showing relative file paths per window). The configuration also introduces a custom tab labeling system with a :TabRename command and updates laststatus to 3 for global statusline compatibility.

Changes:

• Adds lualine plugin configuration with statusline, tabline, and winbar sections
• Implements custom tab labeling with TabRename command supporting manual names, tcd directories, and buffer filenames
• Adds grapple.nvim and grapple-line.nvim for file tagging and tabline integration
• Updates laststatus from 2 to 3 and removes manual winbar setting

The tab_label function expects a tabpage ID (handle), but context.tabnr provides the tab number (1-indexed integer). To get the tabpage ID from the tab number, you need to use vim.api.nvim_list_tabpages()[context.tabnr].

Suggested change

	return tab_label(context.tabnr)
	local tabpages = vim.api.nvim_list_tabpages()
	local tabpage = tabpages[context.tabnr]
	if not tabpage then
	return ""
	end
	return tab_label(tabpage)
