fix(zsh): group just -g recipe completion like bare just

[laurigates]

Fixes just -g <TAB> falling back to the flat clap completion.

What

~/.zfunc/_just (source: dot_zfunc/_just) only took its grouped path when the recipe name sat in word 2:

if [[ ${words[CURRENT]} != -* ]] && (( CURRENT == 2 )); then

So just -g <TAB> landed at word 3 and fell through to just's clap dynamic completer, which returns the global recipes flattened into one values group alongside all 68 CLI flags (154 candidates total). fzf-tab rendered that as a single unusable list — no [group(...)] headers, no ,/. group switching.

How

Adds _just_recipe_position, which walks the words before the cursor and accepts a leading run of justfile-selecting flags:

Flag	Form
-g / --global-justfile	bare
-u / --unstable	bare
-f / --justfile	takes a value
-d / --working-directory	takes a value
--justfile=… / --working-directory=…	inline value

Those flags are collected into _just_dump_args and passed to just --dump, so the group list is read from the same justfile the recipe would actually run from. Anything else — a flag's value under the cursor, a recipe already typed, an unrecognized flag — returns 1 and delegates to the native completer exactly as before.

Verification

Exercised the real function with a stubbed _describe across eight cursor positions (from the chezmoi repo, which has both a local and a global justfile):

Input	Result
just <TAB>	local groups: chezmoi, claude, info, maintain, nvim, plugins, setup, test
just -g <TAB>	global groups: claude, git, plugins ✅
just --global-justfile <TAB>	global groups ✅
just -f ~/.config/just/justfile <TAB>	global groups ✅
just -f <TAB>	→ clap (completing the path argument) ✅
just -g -<TAB>	→ clap (completing a flag) ✅
just -g plugins-list <TAB>	→ clap (recipe arguments) ✅
just plugins-list <TAB>	→ clap (recipe arguments) ✅

Also confirmed the file autoloads clean under zsh -f + compinit, and pre-commit run --files dot_zfunc/_just passes.
