update env vars

* feat(timeouts): execution timeout limits

* fix type issues

* add to docs

* update stale exec cleanup route

* update more callsites

* update tests

* address bugbot comments

* remove import expression

* support streaming and async paths'

* fix streaming path

* add hitl and workflow handler

* make sync path match

* consolidate

* timeout errors

* validation errors typed

* import order

* Merge staging into feat/timeout-lims

Resolved conflicts:
- stt/route.ts: Keep both execution timeout and security imports
- textract/parse/route.ts: Keep both execution timeout and validation imports
- use-workflow-execution.ts: Keep cancellation console entry from feature branch
- input-validation.ts: Remove server functions (moved to .server.ts in staging)
- tools/index.ts: Keep execution timeout, use .server import for security

* make run from block consistent

* revert console update change

* fix subflow errors

* clean up base 64 cache correctly

* update docs

* consolidate workflow execution and run from block hook code

* remove unused constant

* fix cleanup base64 sse

* fix run from block tracespan

 **Sync executions** run immediately and return results directly. These are triggered via the API with `async: false` (default) or through the UI.
 **Async executions** (triggered via API with `async: true`, webhooks, or schedules) run in the background. Async time limits are up to 2x the sync limit, capped at 90 minutes.
