fix: order ui accent before nested config tables

[akbash-bot]

Summary

• emit the ui.accent example before nested [ui.*] tables in --default-config
• add a regression test for the parent-before-child TOML ordering

Checks

• cargo test default_config_lists_ui_accent_before_nested_tables -- --nocapture
• generated --default-config, uncommented ui.accent and [ui.sidebar.spaces] in place, then herdr config check (config: ok)
• cargo fmt --check
• cargo clippy --all-targets --locked -- -D warnings
• just check reached 959 passing tests, then hit the pre-existing live-handoff test harness assumption that test binaries live under <checkout>/target; this issue environment requires an external isolated CARGO_TARGET_DIR

Make the regression test reject duplicate accent documentation.

find returns the first matching block. If the removed later block is reintroduced, accent < sidebar still passes. Count the accent documentation marker and assert that it occurs exactly once before checking the ordering.

Proposed test improvement

 #[test]
 fn default_config_lists_ui_accent_before_nested_tables() {
-    let accent = DEFAULT_CONFIG.find("# accent = \"cyan\"").unwrap();
-    let sidebar = DEFAULT_CONFIG.find("# [ui.sidebar.agents]").unwrap();
+    let accent_marker = "# Accent color for highlights, borders, and navigation UI.";
+    assert_eq!(DEFAULT_CONFIG.matches(accent_marker).count(), 1);
+    let accent = DEFAULT_CONFIG.find("# accent = \"cyan\"").unwrap();
+    let sidebar = DEFAULT_CONFIG.find("# [ui.sidebar.agents]").unwrap();

     assert!(accent < sidebar);
 }

Greptile Summary

The PR corrects the generated default configuration’s TOML ordering and adds focused regression coverage.

• Moves the commented ui.accent example before all nested [ui.*] tables.
• Verifies that the accent example occurs exactly once and precedes the first nested UI table.

Confidence Score: 5/5

The PR appears safe to merge with no actionable correctness or security issues identified.

The generated configuration now places the ui.accent scalar before the first nested UI table, and the regression test directly protects that ordering.
