Pull request overview
This PR expands the public surface area and documentation around semantic error types by re-exporting them via workflow/internal/errors, adding/standardizing world-level error classes in @workflow/errors, and introducing API reference docs for these errors. It also adds DEBUG-gated request timing logs in the Vercel world client and fixes a CLI env var passthrough.
Changes:
- Re-export semantic error types from
workflow/internal/errorsand add new world-level semantic error classes to@workflow/errors. - Add/standardize TSDoc on error classes and add API reference docs pages for the error types.
- Add DEBUG-gated HTTP timing logs in
@workflow/world-verceland passWORKFLOW_LOCAL_BASE_URLthrough CLI inspect env.

Add missing error exports (HookNotFoundError, EntityConflictError, RunExpiredError, TooEarlyError, ThrottleError, RunNotSupportedError, WorkflowWorldError) to workflow/internal/errors. Create new error classes for world-level semantics. Tighten TSDoc comments on all error classes. Add API reference docs for all error types.

EntityConflictError, RunExpiredError, TooEarlyError, and ThrottleError extend WorkflowError instead of WorkflowWorldError, breaking the documented class hierarchy.
