Add Requesty preset

[Thibaultjaigu]

Adds a requesty preset, mirroring the existing openrouter preset.

Requesty (https://requesty.ai) is an OpenAI-compatible LLM router — base URL https://router.requesty.ai/v1, provider/model naming, Authorization: Bearer auth via REQUESTY_API_KEY.

Changes:

• src/cli/requesty.rs (new): a faithful copy of src/cli/openrouter.rs with DEFAULTS set to the Requesty base URL, REQUESTY_API_KEY, ProviderKind::OpenAICompat, default model openai/gpt-4o-mini (verified live).
• src/cli/mod.rs: module declaration + re-export.
• src/main.rs: Requesty clap subcommand variant + into_requesty_args + dispatch arm.
• README.md: usage synopsis + a Requesty mode section.

Verified with cargo +1.92 build (Finished, exit 0), cargo fmt --check clean, and the requesty_defaults_constants unit test passes. (The repo's deps require rustc ≥1.92; I built with that toolchain.)

I work at Requesty. This mirrors the existing OpenRouter provider as closely as possible. Happy to adjust or close it if it's not a fit.

Hey, thank you for adding this in. Requesty seems to have a good free tier so a Github Actions verification would be really good thing to have so it won't break so easily. Could you add that in? You can check how the other providers do the actions and copy paste from there

Added it. There's now a tests/e2e_requesty.rs suite that mirrors e2e_openrouter, plus a .github/workflows/e2e-requesty.yml workflow gated on the test-requesty label (same pattern as the other paid providers) that runs it against the live endpoint using a REQUESTY_API_KEY repo secret. Extended the shared e2e DSL with the requesty judge/builder helpers and noted the new label in the README.

I ran the suite locally against the live Requesty endpoint and it passes (unminifies the fixture and the judge returns EXCELLENT/GOOD). You'll just need to add the REQUESTY_API_KEY secret and apply the test-requesty label for it to run in CI — free-tier keys work fine.

Great, thank you so much! I'll check this out and add the API key to Github Actions on next week

I'll verify with Github Actions when I get to my machine from holidays
