Zig files go to zls as a child process through the protocol client, as every other language does: the in-process ZLS backend goes

lsp_zls.zig (1,522 lines), the zls dependency, build.zig's zls wiring and the import graph it baked into the options only for it, and main.zig's reference go. lsp_client's table gains a zls row (PARDES_LSP_ZIG overrides it); Hover, Rename, Diagnostics, WsSymbols, Lspinfo and gd answer through it (checked with lspprobe and the snapshots against zls 0.16.1-dev). What changes for a user: zls must be on PATH; a completion's rows are zls's candidates at the cursor, where the linked analyser gave each one's declaration; document symbols carry no signature. The Zig snapshots (lsp, lspcomplete, lspcompletemoved, lspdebug, lsprelpath) run the real zls now: lspdebug reads the client's explain and report, lsprelpath spells gr's rows where it spelled a completion's, and their goldens are recorded again (stable over three runs). Lspinfo still opens with its backend line. The ReleaseFast tty binary is 105.35 MB to 96.28 MB, the Debug one 296.5 MB to 245.9 MB. docs/lsp.md, web.md, design.typ and the README say so.
