Add Api.Airforce (unified OpenAI/Anthropic-compatible gateway, free tier)

[AirforceAPI]

Adds Api.Airforce under Inference providers — a unified, OpenAI- & Anthropic-compatible gateway with a permanent free tier (free open-weight models, no credit card) plus pay-as-you-go for 100+ models across text, image, audio and video.

• Base URL: https://api.airforce/v1
• OpenAI SDK-compatible; official SDKs in 8 languages
• Representative free open-weight models listed (GLM-4.7 Flash, Kimi K2.6 Thinking, DeepSeek V3.2, GPT-OSS 120B)

Placed alphabetically at the top of the Inference providers section, matching the existing OpenRouter-style aggregator entry.

Friendly ping — this one has been open for a few weeks and still merges cleanly with no conflicts. Happy to rebase, split it up, or adjust the wording if the entry format needs anything. Thanks for maintaining the list.

Thanks. This PR adds your own product, so I will not merge it as is. I add entries only after independent verification with a real request. Your site documents a free tier at 1 RPM and 1,000 RPD on basic models; I will verify what that actually covers and come back with the outcome. Note the README is generated from data.json, so any change goes there.
