chore(sprint-planning): convert workflow.yaml + instructions.md to unified workflow.md

Step 4 of 9 in the yaml-to-md conversion plan. Merges config
and instructions into a single self-contained workflow.md,
dropping engine scaffolding (critical tags, invoke-protocol).

-## 📚 Document Discovery - Full Epic Loading
+**Goal:** Generate sprint status tracking from epics, detecting current story statuses and building a complete sprint-status.yaml file.
+
+**Your Role:** You are a Scrum Master generating and maintaining sprint tracking. Parse epic files, detect story statuses, and produce a structured sprint-status.yaml.
+
+---
+
+## INITIALIZATION
+
+### Configuration Loading
+
+Load config from `{project-root}/_bmad/bmm/config.yaml` and resolve:
+
+- `project_name`, `user_name`
+- `communication_language`, `document_output_language`
+- `implementation_artifacts`
+- `planning_artifacts`
+- `date` as system-generated current datetime
+- YOU MUST ALWAYS SPEAK OUTPUT in your Agent communication style with the config `{communication_language}`
+
+### Paths
+
+- `installed_path` = `{project-root}/_bmad/bmm/workflows/4-implementation/sprint-planning`
+- `template` = `{installed_path}/sprint-status-template.yaml`
+- `checklist` = `{installed_path}/checklist.md`
+- `tracking_system` = `file-system`
+- `project_key` = `NOKEY`
+- `story_location` = `{implementation_artifacts}`
+- `story_location_absolute` = `{implementation_artifacts}`
+- `epics_location` = `{planning_artifacts}`
+- `epics_pattern` = `epic*.md`
+- `status_file` = `{implementation_artifacts}/sprint-status.yaml`
+
+### Input Files
+
+| Input | Path | Load Strategy |
+|-------|------|---------------|
+| Epics | `{planning_artifacts}/*epic*.md` (whole) or `{planning_artifacts}/*epic*/*.md` (sharded) | FULL_LOAD |
+
+### Context
+
+- `project_context` = `**/project-context.md` (load if exists)
+
+---
+
+## EXECUTION
+
+### Document Discovery - Full Epic Loading
 
 **Strategy**: Sprint planning needs ALL epics and stories to build complete status tracking.
