Add completion/tests/ harnesses that exercise the engine protocol and every shell wrapper without a TTY: the engine via `task __complete`, bash/zsh by stubbing the completion-system helpers, fish via `complete -C`, and PowerShell via the completion API. A `test:completion` task and a matching CI job (with a strict mode that fails when an expected shell is missing) run them all. Writing the suite surfaced and fixed real wrapper bugs: - fish: `math` has no bitwise `&`, so every directive check errored; test bits with integer division + modulo instead. Also filter FilterFileExt results ourselves, as __fish_complete_suffix only prioritizes the extension. - powershell: `Get-ChildItem -Include` is ignored without -Recurse, so file extension filtering returned nothing; filter with Where-Object instead. - bash: guard empty-array expansion so completion with zero candidates does not trip `set -u` on bash 3.2. Also name the completion directive bits (NO_SPACE, FILTER_FILE_EXT, …) in every wrapper instead of using raw numbers.
