## Problem
lib/services/queue.ts was not updated during workflow refactor (#147) and still
used hardcoded queue labels: QueueLabel type, QUEUE_PRIORITY constant.
## Solution
- Add getQueueLabelsWithPriority() to derive queue labels from workflow config
- Add getQueuePriority() to get priority for any label
- Update getTaskPriority() and getRoleForLabel() to accept workflow config
- Update fetchProjectQueues() to use workflow-derived labels
- Add getTotalQueuedCount() helper
## Files Changed
- lib/services/queue.ts — use workflow config for all queue operations
- lib/tools/status.ts — handle dynamic queue labels, include queueLabels in response
## Backward Compatibility
- QueueLabel type kept as deprecated alias
- QUEUE_PRIORITY kept as deprecated constant
- All functions accept optional workflow parameter, default to DEFAULT_WORKFLOW
- Introduced a new heartbeat service that runs at defined intervals to perform health checks on workers and fill available task slots based on priority.
- Added a health tool to scan worker health across projects with optional auto-fix capabilities.
- Updated the status tool to provide a lightweight overview of worker states and queue counts without health checks.
- Enhanced task creation tool descriptions to clarify task state handling.
- Implemented tests for the work heartbeat logic, ensuring proper project resolution, worker state management, and task prioritization.
- Updated import paths for task management providers in task-comment, task-create, and task-update tools.
- Removed deprecated task-complete and task-pickup tools, replacing them with work-finish and work-start tools for improved task handling.
- Enhanced work-finish and work-start tools to streamline task completion and pickup processes, including context-aware detection and auto-scheduling features.
- Updated package.json to include build scripts and main entry point.
- Modified tsconfig.json to enable output directory, declaration files, and source maps for better TypeScript support.
