When tool calls are added to the conversation history, map providerMetadata
to providerOptions following the AI SDK convention. This fixes Gemini thinking
models that require thoughtSignature to be preserved across multi-turn tool calls,
preventing the error 'function call is missing a thought_signature'.
Fixes#727
Step sourcemaps don't work in Vercel production deployments.
Previously the function returned true for most frameworks on all
Vercel deployments. Now it correctly returns false for production
builds while preserving the existing behavior for preview builds.
* Refactor e2e tests for errors
* Improve step error tests to check workflow return value
Step error workflows now catch the error and return message/stack,
making assertions cleaner. Tests verify both:
- Workflow return value (caught error message)
- CLI step result (original stack with function names)

* Add assertion for stack trace in caught step error
With the fix in step.ts that propagates original stack traces,
we can now verify that caught step errors include function names
directly in the workflow return value (not just via CLI).

* Fix: When a step handler is re-invoked after max retries are exhausted, the step_failed event doesn't include a stack trace, breaking stack trace propagation for this edge case.
This commit fixes the issue reported at packages/core/src/runtime/step-handler.ts:127-146
## Stack trace loss in step_failed event when max retries are exceeded
**What fails:** Step handler does not include stack property in step_failed event when step is re-invoked after max retries exhausted, causing FatalError in workflow to lose original stack trace
**How to reproduce:**
1. Create a step that always fails with an error that includes a stack trace
2. Exhaust all retry attempts (e.g., maxRetries = 3, so 4 total attempts)
3. The step handler is re-invoked (attempt > maxRetries + 1)
4. This triggers the edge case at lines 127-146 in step-handler.ts
5. A step_failed event is created with fatal: true but without stack property
6. When step.ts processes this event (lines 103-104), the stack remains unset since event.eventData.stack is undefined
**Result:** FatalError created in workflow has default stack (from step.ts) instead of original error stack from step execution
**Expected:** Stack trace should be propagated consistently across all error paths. All other step_failed events with fatal: true include stack property (lines 311-313 and 351-353), but edge case was missing it.
**Root cause:** When step handler is re-invoked after max retries exhausted (attempt > maxRetries + 1), the code creates a step_failed event without including step.error?.stack, which contains the previous error information from the last failed attempt. Other code paths capture this correctly.

* Enable source maps for step bundles and validate in e2e tests
- Move sourcemap generation from intermediate workflow bundle to steps bundle
- Enhance step error tests to validate function names and source files in stack traces
- Remove isLocalDeployment() checks since source maps now work in dev mode

* Fix step error source map checks for local prod builds
Add hasStepSourceMaps() helper that correctly identifies when source maps
are expected to work:
- Vercel prod: works (production builds have proper source maps)
- Local dev: works (DEV_TEST_CONFIG is set, uses step bundle with inline source maps)
- Local prod: doesn't work (nitro/bundler output doesn't preserve source maps)

### Key Changes
**Generation Settings**
- Support for `temperature`, `maxOutputTokens`, `topP`, `topK`, `presencePenalty`, `frequencyPenalty`, `stopSequences`, `seed` at constructor and per-stream level
**Step Control**
- Added `maxSteps` to limit LLM calls (default: unlimited for backwards compatibility)
- Added `toolChoice` (`auto`, `none`, `required`, or specific tool)
- Added `activeTools` to filter available tools per-stream call
**Callbacks**
- `onChunk` - called for each stream chunk
- `onStepFinish` - called after each step completes
- `onFinish` - called when all steps complete
- `onError` - called on errors
- `onAbort` - called when aborted via `AbortSignal`
**Structured Output**
- Added `experimental_output` with `Output.object({ schema })` for parsing structured responses
**Context & Telemetry**
- Added `experimental_context` to pass data to tool executions
- Added `experimental_telemetry` for observability
**Stream Result**
- `stream()` now returns `{ messages, steps, experimental_output }` instead of just `{ messages }`
**Other**
- `prepareStep` can now override generation settings, toolChoice, and context
- Added `experimental_repairToolCall` for handling malformed tool calls
- Enabled file, source, and tool input streaming chunks
- Exported all new types from `@workflow/ai`
