output(dump): stale dump_children reference in depth-limit test comment

[dekobon]

Summary

A test comment in src/output/dump.rs refers to a dump_children
function that no longer exists; the depth - 1 decrement it describes
lives in dump_tree_helper since the #700 recursive-to-iterative
rewrite.

Location

• src/output/dump.rs:457-462 (test dump_output_depth_limits_recursion)

Evidence

// depth=1 renders the node and stops before its children; depth=0 renders nothing.
// This is the only positive-depth path in production, and it is what the `depth - 1`
// decrement in `dump_children` guards — pin it explicitly.

rg -n "dump_children" src/ matches only this comment — there is no such
function. The depth decrement (let child_depth = depth - 1;) is in
dump_tree_helper (src/output/dump.rs:160). #700 inlined the former
per-children recursion into the single iterative walk, but this comment
kept the old function name.

Expected Behavior

The comment should name dump_tree_helper (or "the iterative walk"),
matching the post-#700 structure.

Actual Behavior

The comment cites a non-existent dump_children, sending a reader
searching for a function that was removed.

Impact

Minor reader-confusion / stale-comment maintenance hazard in test code.

Resolution

Fixed in 7a41184: test comment now names dump_tree_helper's iterative walk instead of the removed dump_children.

General Plan for Fix

Root Cause

#700 inlined the former per-children recursion into the iterative
dump_tree_helper, but the dump_output_depth_limits_recursion test
comment kept the old dump_children function name.

Implementation Steps

1. Edit the comment at src/output/dump.rs:461-462 to name
   dump_tree_helper (or "the iterative walk's depth - 1 decrement").

Tests to Add/Update

• None (comment-only change; the test body already verifies the behavior).

Verification

• rg -n "dump_children" src/ returns no matches
• cargo test -p big-code-analysis passes

[dekobon]

Fixed in 7a41184. The dump_output_depth_limits_recursion test comment referred to dump_children, which no longer exists after the #700 recursive→iterative rewrite; the depth - 1 decrement now lives in dump_tree_helper's iterative walk (dump.rs:160). Updated the comment. Confirmed rg dump_children src/ now matches nothing.

Fixed and merged to main in #957. GitHub did not auto-close this from the batched commit's single Fixes #a #b #c … trailer (only the first referenced issue auto-closes); closing manually. See the Resolution section in the body for details.
