perf(cache): remove eager response store tag index

[james-elicx]

Summary

• stop writing one SQLite row for every cache tag on every publication
• select tagged entries from stored metadata only during explicit refresh and purge mutations
• retain tag invalidation timestamps for soft-tag correctness
• preserve the old tables for safe rollback compatibility without backfilling or writing them

Validation

• vp check packages/workers-response-store/src/metadata-do.ts packages/workers-response-store/tests/e2e.test.mjs
• pnpm --filter @vinext/workers-response-store run build:examples
• pnpm --filter @vinext/workers-response-store exec vitest run tests/e2e.test.mjs tests/service-binding-e2e.test.mjs
