Engine: - Emit DirectiveKeepOrder for task variables so the `requires` declaration order is preserved instead of being sorted by the shell. - Return full `--flag=value` candidates for the inline `--output=` form so all shells match against the whole current token. - Add `--no-aliases` / `--no-descriptions` completion flags (via complete.Options) parsed from the __complete invocation; the zsh wrapper maps its show-aliases and verbose zstyles onto them. - Skip Taskfile setup when completing flags (NeedsTaskfile) and load the task list lazily; drop unused parameters; document exported identifiers. Shell wrappers: - zsh: reindent to tabs (.editorconfig), bridge zstyles to engine flags. - fish: reindent to 2 spaces, handle every file-completion directive in the wrapper (--no-files disables the native fallback), drop the duplicated yml/yaml extension list now that it lives only in the engine. - bash: prefix-filter by hand to preserve values containing spaces, exclude `=` from word breaks so `--output=` reaches the engine as one token. - powershell: filter candidates by the current word, fall back to file completion for DirectiveDefault. NoSpace is not representable in fish/PowerShell completion APIs; documented in the wrappers.
