fix(tests): pass models to combo create in cli-combo-command (#9985)

[jonlwheat2-gif]

🔴 Issue

Unit test tests/unit/cli-combo-command.test.ts — 3 of 5 tests fail with AssertionError: Expected values to be strictly equal: 1 !== 0:

• combo create inserts a new combo via db module (line 41)

• combo delete removes the combo (line 73)

• combo switch updates active combo when server is offline (line 96)

• Linked issue: 🔴 Release branch not green: release/v3.8.50 diegosouzapw/OmniRoute#9985 (base-red report)

• Root-cause PR: fix(api): refuse creating a routing combo without any model diegosouzapw/OmniRoute#11162 (b3844550d) — made combo create refuse a combo with no targets ("combo create requires at least one target..."). It updated 5 sibling combo tests but missed this file. All three failures call runComboCreateCommand(..., {}) with no models → the command now returns exit code 1; delete and switch fail as collateral because they each create a combo first as setup.

• Reported by: reviewer on PR fix(ci): green the release/v3.8.50 base (#9985) diegosouzapw/OmniRoute#11201; written up in detail as base-red: cli-combo-command.test.ts — 3 testes falham com 1 !== 0 desde #11162 (combo create passou a exigir models) diegosouzapw/OmniRoute#11203 (deliberately not opening a competing PR since fix(ci): green the release/v3.8.50 base (#9985) diegosouzapw/OmniRoute#11201 owns the base-green work)

📍 Where to look

File: tests/unit/cli-combo-command.test.ts — lines 41, 60, 77, 100 (the four runComboCreateCommand calls).

🟢 What was fixed

  test("combo create inserts a new combo via db module", async () => {
    ...
-    const result = await runComboCreateCommand("my-combo", "priority", {});
+    // #11162: combo create refuses combos without any model — pass a model
+    // like the sibling tests updated in that commit.
+    const result = await runComboCreateCommand("my-combo", "priority", {
+      models: ["openai/gpt-4o-mini"],
+    });

Same treatment for the dup-combo (both calls), to-delete, and my-switch create calls — mirroring exactly what diegosouzapw#11162 did to its sibling tests.

• Red (before): runComboCreateCommand(name, strategy, {}) — no models → refused with exit 1
• Green (after): models: ["openai/gpt-4o-mini"] passed → create succeeds → delete/switch setup works

✅ Verification (Linux, Docker, Node 24.19.0)

• Pristine file at tip 79c5bdf68: 2 pass / 3 fail (matches reviewer's report)
• With this fix: 5 pass / 0 fail
