# fn-13-pxj.5 Add CI tests for async control commands

## Description
Add CI tests for all new async control commands.

**IMPORTANT**: Tests must be jq-free. Use Python for JSON parsing to maintain Windows Git Bash compatibility.

### Implementation

**In `plugins/flow-next/scripts/ci_test.sh`:**

1. `test_status_command`:
   ```bash
   test_status_command() {
     $FLOWCTL status
     [[ $? -eq 0 ]] && pass "status command" || fail "status command"
   }
   ```

2. `test_status_json`:
   ```bash
   test_status_json() {
     output=$($FLOWCTL status --json)
     # Use Python to validate JSON (not jq)
     echo "$output" | python3 -c 'import json,sys; json.load(sys.stdin)' 2>/dev/null
     [[ $? -eq 0 ]] && pass "status --json" || fail "status --json invalid JSON"
   }
   ```

3. `test_ralph_pause_resume_commands`:
   ```bash
   test_ralph_pause_resume_commands() {
     # Create mock run directory
     mkdir -p scripts/ralph/runs/test-run
     echo "iteration: 1" > scripts/ralph/runs/test-run/progress.txt
     
     # Test pause
     $FLOWCTL ralph pause --run test-run
     [[ -f scripts/ralph/runs/test-run/PAUSE ]] && pass "ralph pause" || fail "ralph pause"
     
     # Test resume
     $FLOWCTL ralph resume --run test-run
     [[ ! -f scripts/ralph/runs/test-run/PAUSE ]] && pass "ralph resume" || fail "ralph resume"
     
     # Test stop
     $FLOWCTL ralph stop --run test-run
     [[ -f scripts/ralph/runs/test-run/STOP ]] && pass "ralph stop" || fail "ralph stop"
     
     # Cleanup
     rm -rf scripts/ralph/runs/test-run
   }
   ```

4. `test_task_reset`:
   ```bash
   test_task_reset() {
     # Create epic and task
     epic=$($FLOWCTL epic create --title "Reset test" --json | python3 -c 'import json,sys; print(json.load(sys.stdin)["id"])')
     task=$($FLOWCTL task create --epic $epic --title "Test task" --json | python3 -c 'import json,sys; print(json.load(sys.stdin)["id"])')
     
     # Complete task
     $FLOWCTL start $task
     $FLOWCTL done $task
     
     # Reset
     $FLOWCTL task reset $task
     status=$($FLOWCTL show $task --json | python3 -c 'import json,sys; print(json.load(sys.stdin)["status"])')
     [[ "$status" == "todo" ]] && pass "task reset" || fail "task reset: status=$status"
     
     # Cleanup: close epic to avoid polluting state
   }
   ```

5. `test_task_reset_cascade`:
   ```bash
   test_task_reset_cascade() {
     # Create epic with dependent tasks (A <- B)
     # Complete both
     # Reset A with --cascade
     # Verify both reset to todo
   }
   ```

6. `test_task_reset_in_progress_error`:
   ```bash
   test_task_reset_in_progress_error() {
     # Create and start task (in_progress)
     # Attempt reset, expect failure (exit code != 0)
   }
   ```

### Key Patterns
- Use `python3 -c 'import json,sys; ...'` instead of `jq` for JSON parsing
- Use `python3 -c 'import json,sys; print(json.load(sys.stdin)["field"])'` to extract fields
- Follow existing pass()/fail() patterns

### Key Files
- `plugins/flow-next/scripts/ci_test.sh`
## Acceptance
- [ ] `test_status_command` passes
- [ ] `test_status_json` validates JSON output (using Python, not jq)
- [ ] `test_ralph_pause_resume_commands` tests pause/resume/stop
- [ ] `test_task_reset` tests basic reset flow
- [ ] `test_task_reset_cascade` tests cascade behavior
- [ ] `test_task_reset_in_progress_error` tests error on in_progress
- [ ] All tests registered in test runner
- [ ] `./ci_test.sh` passes with all new tests
- [ ] No jq dependency anywhere in tests
## Done summary
- Added 9 new CI tests for async control commands
- Tests: status, ralph pause/resume/stop, task reset (basic + in_progress error), epic add-dep/rm-dep
- All jq-free (Python JSON parsing for Windows Git Bash compatibility)

Why: Verify new async control commands work correctly

Verification: CI 40/40 (was 31/31, +9 new tests)
