Karthik Kalyan 89f4726b73 Fix compressed workflow error display (#2680 )

* Fix compressed workflow data display

* Add OSS web no-key hydration regression

* Scope compression normalization to read paths; tidy hydration

Address review feedback on the compressed-data fix:

- world-vercel: keep gzip/zstd decompression on the o11y/display read
  paths (getStep/getRun/getEvent/getWorkflowRunEvents/getHook) but not on
  the runtime event-append path (world.events.create, createStep,
  updateStep). That path is runtime-only and re-hydrates every payload via
  the decompress-aware helpers, so decompressing at the adapter was
  redundant work on the TTFB-sensitive run_started/inline-delta path and
  skewed the runtime's deserialize compression telemetry to `codec: none`.
  deserializeStep is now shape-only; normalizeStepData runs in the read
  filter. Adds a regression test pinning the write-path pass-through.
- serialized-data: drop dead `errorRef`/`metadataRef` normalization (refs
  are descriptor objects, never compressed byte payloads).
- web: in the wait-entity path, filter events by correlationId before
  hydrating so an encryption key doesn't decrypt the whole event page.

Decompress gzip- and zstd-prefixed serialized data returned from Vercel Workflow storage, and route OSS web hydration through the async WASM-capable path for compressed payloads.
