fix(filter): insert path from filter.paths into self.paths

[dpetka2001]

Description

Here we see that we insert the paths into filter instead of self.paths

snacks.nvim/lua/snacks/picker/core/filter.lua

Lines 34 to 44 in b96bd54

	self.paths = {}
	local cwd = filter and filter.cwd
	self.cwd = type(cwd) == "string" and cwd or opts.cwd or uv.cwd() or "."
	self.cwd = vim.fs.normalize(self.cwd --[[@as string]], { _fast = true })
	if not self.all and filter then
	self.buf = filter.buf == true and 0 or filter.buf --[[@as number?]]
	self.buf = self.buf == 0 and vim.api.nvim_get_current_buf() or self.buf
	self.file = self.buf and vim.fs.normalize(vim.api.nvim_buf_get_name(self.buf), { _fast = true }) or nil
	for path, want in pairs(filter.paths or {}) do
	table.insert(filter, { path = vim.fs.normalize(path), want = want })
	end

and later on here

snacks.nvim/lua/snacks/picker/core/filter.lua

Lines 90 to 94 in b96bd54

	if self.opts.paths then
	for _, p in ipairs(self.paths) do
	if (path:sub(1, #p.path) == p.path) ~= p.want then
	return false
	end

we check self.paths to get the path.

This was causing issues to not correctly filter out the already defined paths and I was able to see, for example the scratch buffer files in the pickers.

Another thing I noticed is that in the smart picker one has to redefine in his personal configuration the filter.paths from recent picker (otherwise I'm able to see the scratch buffers from stdpath("data")/scratch in the smart picker), presumably because there's something weird going on with the merge of the sources configs, since filter.paths is a list.

Unfortunately, my knowledge is limited and tried but couldn't quite understand what's going on with the way the merging is done.
