This commit implements issue #456, adding two related capabilities to the uwf CLI:
1. **Background execution mode** for `uwf thread step` (via `--background` flag)
- Spawns agent execution in a detached background process
- Returns immediately with thread ID and background status
- Maintains marker files to track running processes
- Supports `--count` option to run multiple steps in background
- Prevents concurrent execution of the same thread
2. **Running threads query** command (`uwf thread running`)
- Lists all threads currently executing in background
- Returns thread ID, workflow, current role, PID, and start time
- Automatically filters out stale markers (dead processes)
- Empty list when no threads are running
**Key changes:**
- **workflow-protocol**: Added `RunningThreadItem`, `RunningThreadsOutput` types
Updated `StepOutput` to include `background: boolean | null` field
- **cli-workflow/background**: New module for process management
- Marker file creation/deletion (atomic operations)
- PID liveness checking
- Stale marker cleanup
- Running threads query
- **cli-workflow/commands/thread**:
- Updated `cmdThreadStep` to support `--background` and `--_background-worker` flags
- Added `cmdThreadStepBackground` for spawning detached processes
- Added `cmdThreadRunning` to list running threads
- Updated `cmdThreadKill` to terminate background processes
- **cli-workflow/cli**: Added CLI routing for new commands and flags
**Integration:**
- `uwf thread kill` now terminates background processes before archiving
- Foreground execution checks for existing background process and fails if found
- Background worker creates/cleans up marker files automatically
- Marker files stored in `~/.uncaged/workflow/running/*.json`

Extract helper functions (resolveThreadId, getThreadHead, listThreadSteps,
displayStepDetails, displayThreadRead) to reduce nesting and improve
readability. Also adds test coverage for the refactored functions.
Fixes#446
- Add 4-strategy resolution priority: CAS hash → file path → local discovery → global registry
- Add helper functions: isFilePath, workflowFileExists, findWorkflowInDir, findWorkflowInParents
- Refactor resolveWorkflowCasRef to support direct hash, explicit paths, and parent traversal
- Add comprehensive test suite with 24 tests covering all strategies and edge cases
- Support .workflow/ and .workflows/ directories with .yaml/.yml extensions
- All 60 tests pass across 5 test files

- Disable aliasDuplicateObjects in YAML stringify to prevent &a1/*a1
anchors when multiple steps have identical output
- Fix unused discoverAgents function (prefixed with _) and format issue
in setup.ts
- StepRecord adds edgePrompt field (backward compat: defaults to "")
- StepNode CAS schema includes edgePrompt
- writeStepNode persists ctx.edgePrompt
- buildHistory exposes edgePrompt in StepContext
- buildBuiltinMessages reconstructs multi-turn moderator↔agent conversation:
system = role prompt + output format (stable prefix)
per prior visit: user (edgePrompt + inter-step summary) + assistant (output)
current: user (edgePrompt + recent summary)
- Zero extra persistence — pure function of CAS chain
- Stable prefix for LLM prompt cache hits
- 10 builtin tests pass, all other package tests pass
Add --count/-c flag to 'uwf thread step' for running N steps in one
invocation, stopping early if $END is reached.
- cmdThreadStep now loops up to count times, delegates to cmdThreadStepOnce
- CLI parses -c/--count, defaults to 1 (backward compatible single output)
- Validation rejects 0, negative, and non-integer counts
- 7 new tests covering CLI parsing and count validation
Fixes#373
Co-authored-by: uwf-hermes (solve-issue workflow)
- Add .workflows/*.yaml scanning from project root (cwd)
- Resolution: project-local first, then global registry
- On-the-fly CAS materialization for local workflows
- Filename/name consistency check
- uwf workflow list shows origin (local/global)
Fixes#365
Breaking change per review:
- Remove systemPrompt from RoleDefinition entirely
- identity/prepare/execute/report are now required (string, not nullable)
- Remove all legacy fallback logic in buildRolePrompt
- Simplify validate.ts, workflow.ts materialize
- Migrate all test fixtures and example workflows
Refs #359
- Extend RoleDefinition with identity, prepare, execute, report fields
- Make systemPrompt optional (nullable) for four-phase workflows
- Update ROLE_DEFINITION JSON Schema (all new fields optional)
- Update validate.ts to accept new fields
- Update workflow.ts to strip null fields before CAS storage
- Update thread read to prefer identity over systemPrompt
- Add --version flag to uwf CLI
- Bump all packages to 0.5.0
