fix(cloudflare/workers): support ratelimit upload bindings

[agcty]

Adds the missing ratelimit Worker script upload binding variant to the generated Cloudflare Workers SDK.

• Patches putScript request metadata bindings through the existing Cloudflare patch system
• Regenerates the Workers service and emitted OpenAPI spec
• Covers request encoding so namespaceId is sent as namespace_id

Verification update:

• Build passed: bun --filter @distilled.cloud/core build.
• Focused test passed: bun --filter @distilled.cloud/cloudflare test --run test/client-api.test.ts.
• Typecheck passed: bun --filter @distilled.cloud/cloudflare typecheck.
• Check passed: bun --filter @distilled.cloud/cloudflare check.

This unblocks Worker uploads that include ratelimit bindings for alchemy-run/alchemy-effect#238.
