data: add Sarvam AI startup program

[stillfoundry]

Summary

• add Sarvam AI as a new AI/ML vendor
• add the named Sarvam AI Startup Program with exactly one benefit-led offer
• model 6–12 months of API credits matched to startup scale, priority engineering support, production APIs, and launch visibility

Evidence

The current first-party English-language program page states the 6–12 month credit duration and each included benefit. The Sarvam homepage supports the vendor description and primary domain. This is a fresh contribution with new IDs; it does not reuse the closed PR #55 branch or IDs.

Validation

• Sourcey digest-pinned verifier: status valid, vendors 1, programs 1, offers 1
• both first-party source URLs return HTTP 200
• git diff --check passes
• DCO sign-off present

Closes #549

Thanks for this. sourcey/validation is green, but the evidence pass for this head could not locate support for every submitted fact, so sourcey/admission cannot go green yet.

Uncovered on the record: /economics.

Fix it on this same branch: either cite a public page that states the fact (add the URL to sources and reference its source_id from the record that needs it), or change the record to what the cited pages do say. Push to the branch and the checks re-run automatically.

Updated the same branch at 9390c10. I narrowed the uncovered economics metadata by replacing the bespoke negative consideration statement with the repository-standard unknown-consideration wording; the four benefits remain directly supported by the current server-rendered Sarvam startup-program page. The exact digest-pinned verifier passes with status valid (1 vendor, 1 program, 1 offer).
