perf(response-store): project refresh candidates

[james-elicx]

Summary

• return only reservation fields from refresh candidate selection
• avoid loading and parsing response headers, revalidator arguments, cache tags, and response metadata before reservation
• preserve filtering and the existing missing-revalidator error behavior
• add an E2E assertion for the exact lightweight RPC shape

Performance

Manual refresh now transfers five small fields per candidate instead of full stored entries. The full entry is still read exactly where it is required, during reserveRegeneration().

Validation

• npm run build:examples
• vp test run tests/e2e.test.ts tests/service-binding-e2e.test.ts (79 passed)
• npm run check
• git diff --check

This is Cloudflare storage-backend query work; there is no corresponding Next.js behavior or test to port.
