cursor: Test Grok 4.6 Fast parameter mapping

[jontonsoup]

Summary

• Add regression coverage for the Grok 4.6 Fast Cursor wire contract already implemented on dev: base model grok-4.6 with separate effort and fast parameters.
• Assert the static Cursor catalog exposes grok-4.6-fast.

Verification

• ./node_modules/.bin/bun test tests/cursor-effort-suffix.test.ts tests/cursor-discovery.test.ts tests/cursor-static-catalog.test.ts (23 passed)
• ./node_modules/.bin/bun run typecheck
• Full bun run test attempted; unrelated loopback-server tests cannot bind ephemeral port 0 in this sandbox (EADDRINUSE).

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed. (No docs change: production support is already present on dev; this PR adds missing regression coverage.)
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. (Tests only; no security boundary changed.)

Walkthrough

The PR adds Cursor test coverage for grok-4.6-fast discovery and request translation. It verifies the grok-4.6 model ID and separate effort and fast parameters.

Changes

Cursor Grok 4.6 Fast coverage

Layer / File(s)	Summary
Discovery and request-parameter regression tests tests/cursor-discovery.test.ts, tests/cursor-effort-suffix.test.ts	The discovery test requires grok-4.6-fast in the static model seed. The effort-suffix test verifies the grok-4.6 model ID and separate effort and fast parameters for high-effort requests.
