refactor: polish lsp.lua and mason-extras.lua

- Restore pyright inline comments explaining Ruff delegation
- Add header comment documenting mason-lspconfig/vim.lsp.config coupling
- Unwrap lsp.lua outer spec table (consistency with blink-cmp.lua, conform.lua)
- pcall mason-registry.get_package (defensive against unknown package name)
- Split inline autocmd opts across lines (style)
