feat(tui): show total tokens for each period

[jimyag]

Summary

Show total tokens for each hourly, daily, weekly, monthly, and yearly row in the aggregate TUI table, so usage can be compared across periods without adding the token columns manually.

Changes

• Add an always-visible Total Tks column and footer total using cached + input + output tokens, matching the existing summary calculation. Reasoning tokens remain separate.
• Include the new column in table width calculations and cover its row and footer values with a rendering test.
• Adjust two existing rendering test widths for the wider table.

Verification

• cargo fmt --all --check — passed
• cargo clippy --quiet -- -D warnings — passed
• cargo build --quiet — passed
• cargo test --quiet — passed (473 tests)
• cargo doc --quiet — passed
• git diff --check — passed

Notes

Review focus: the total should follow the existing TUI summary formula and stay aligned when optional columns are hidden.

Summary by CodeRabbit

• New Features
  • Added a Total Tks column to aggregate statistics, showing the combined cached, input, and output tokens for each period.
  • Added total token counts to the aggregate table’s summary row.
  • Best-value highlighting now considers combined token totals.

📝 Walkthrough

Walkthrough

The aggregate TUI table adds a “Total Tks” column. It sums cached, input, and output tokens for each period and the footer, highlights the highest total, updates column sizing, and adds coverage for the rendered values.

Changes

Aggregate token totals

Layer / File(s)	Summary
Total token calculation and rendering src/tui.rs	The aggregate table calculates combined token totals, tracks the best-total period, renders the new column, updates the footer, and includes the column in layout sizing.
Aggregate table validation src/tui/tests.rs	Tests verify period and footer totals. Existing layout tests use wider table bounds for the added column.

The TUI now displays combined cached, input, and output token totals for each aggregate period and the footer while keeping reasoning tokens separate. The change is presentation-only with no remaining merge-blocking risk.

Cached, input, and output now glow
A new column hops into view
The footer counts every token too
Best values shine bright in the row}

346-360: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Assert each Total cell exactly.

contains("330") also accepts an incorrect value such as 1330. Extract the Total cell and compare its trimmed value with "330".

Proposed test change

-    assert!(
-        period
-            .chars()
-            .skip(total_column)
-            .take(9)
-            .collect::<String>()
-            .contains("330")
-    );
-    assert!(
-        footer
-            .chars()
-            .skip(total_column)
-            .take(9)
-            .collect::<String>()
-            .contains("330")
-    );
+    let period_total = period
+        .chars()
+        .skip(total_column)
+        .take(9)
+        .collect::<String>();
+    let footer_total = footer
+        .chars()
+        .skip(total_column)
+        .take(9)
+        .collect::<String>();
+    assert_eq!(period_total.trim(), "330");
+    assert_eq!(footer_total.trim(), "330");

Based on learnings: prefer exact assertions in Rust tests.
