--no-trunc is not yet supported with --tree

Error message

--no-trunc is not yet supported with --tree

What it means

Second check in shouldUseTree(): the experimental `--tree` view does not yet implement --no-trunc, so combining them is rejected. The tree layout controls its own truncation and ignores the global flag, hence the explicit guard.

Solutions

1. Drop --no-trunc when using --tree
2. Drop --tree if you require untruncated output
3. Scope --no-trunc to non-tree invocations only

Example fix

// before
docker images --tree --no-trunc
// after
docker images --tree

if options.tree && options.noTrunc {
    return errors.New("--no-trunc is not supported with --tree")
}

When it happens

Trigger: `docker images --tree --no-trunc`.

Common situations: A wrapper script that injects --no-trunc globally for untruncated IDs clashes with the tree renderer.
