Fixed

Rate limiter now accepts configurable rateLimitMax and rateLimitWindow via constructor options (was hardcoded at 100).
CLITransport tests now work cross-platform (Windows + Unix).
35 TypeScript errors resolved across core modules:
- ProviderConfig type aligned with tiers record structure.
- DurableWorkflow async status checks no longer produce unreachable-code errors.
- RAGIndex metadata spread order fixed.
- AgentRouter.query() call signature corrected.
- Embedder constructor called with required logger argument.
- SettingsManager type casts use unknown intermediate for safety.
- MCPPool stdio stream type narrowing added.
- Forge agent scoring uses getRecentTasks() instead of non-existent property.
- Eval test files annotated with explicit types.
