Subject: [PATCH] feat(xai): add grok-4.3 and grok-4.3-latest to
 model_prices_and_context_window.json

xAI's docs page now lists grok-4.3 as the recommended chat / coding model:
"We strongly recommend all API callers use grok-4.3. It is the most
intelligent and fastest model we've built." (https://docs.x.ai/docs/models)

Pricing/specs sourced from xAI's published model metadata:
  - input:  $1.25 / 1M tokens (<=200k),  $2.50 / 1M tokens (>200k)
  - output: $2.50 / 1M tokens (<=200k),  $5.00 / 1M tokens (>200k)
  - cached: $0.20 / 1M tokens (<=200k),  $0.40 / 1M tokens (>200k)
  - context: 1,000,000 tokens
  - capabilities: vision, reasoning, function calling, structured outputs,
    prompt caching, web search

Adds two entries: `xai/grok-4.3` (canonical) and `xai/grok-4.3-latest` (alias),
mirroring the pattern used for the rest of the xAI/Grok-4 family.
