Refactor AI gateway provider definitions

[chrarnoldus]

Summary

• move each static AI gateway provider definition into providers/definitions
• update consumers to import provider definitions directly without re-exports
• isolate provider lookup in try-get-provider-by-id.ts

Testing

• Not run locally; CI will handle validation as requested.
• git diff --check

Code Review Summary

Status: No Issues Found | Recommendation: Merge

The incremental commit updates the previously stale provider-definitions.ts references in ENVIRONMENT.md to the exact providers/definitions/openrouter.ts, longcat.ts, and streamlake.ts modules; all three paths exist and no new issues were introduced.

• ENVIRONMENT.md - previous stale-path finding resolved; paths verified against providers/definitions/

Status: 1 Issue Found | Recommendation: Address before merge

Executive Summary

No runtime or logic defects found in the refactor; provider definitions were moved byte-for-byte into providers/definitions/, but ENVIRONMENT.md still points readers at the deleted provider-definitions.ts module.

SUGGESTION

File	Line	Issue
ENVIRONMENT.md	267, 270, 271	References to the deleted apps/web/src/lib/ai-gateway/providers/provider-definitions.ts are now stale. Update them to the new modules, e.g. providers/definitions/openrouter.ts, providers/definitions/longcat.ts, and providers/definitions/streamlake.ts. This file is unchanged by the PR, so it is reported summary-only (no valid diff line to anchor).
