Update model inventory for Gemini 3.7 Flash and Grok 4.6

[Copilot]

Live Copilot model inventories include grok-4.6 and gemini-3.7-flash, but the cached pricing catalogs did not. gemini-3.7-flash was also missing the dedicated generation alias used by adjacent Gemini Flash releases.

• Model pricing

  • Add grok-4.6 to both models.json mirrors.
  • Add gemini-3.7-flash to both models.json mirrors.
  • Keep pkg/cli/data/models.json and actions/setup/js/models.json synchronized.

• Alias inventory

  • Add a dedicated exact-generation alias:

    "gemini-3.7-flash": [
      "copilot/gemini-3.7*flash*",
      "google/gemini-3.7*flash*",
      "gemini/gemini-3.7*flash*"
    ]

• Coverage

  • Extend focused model pricing and alias tests for the new entries.
  • Add a patch changeset for the inventory update.

• Fixes [model-inventory] Model alias inventory update - 2026-08-16 #52992
