feat(registry): scaffold HR workflow registry with assessment loop

Add workflow entries for INTENT assessment and automation-roadmap phases,
workflows.yaml index, assessment-loop stages, and capability.hr.workflow-catalog
for reuse-surface federation. Completes HUMAN-WP-0002.

+# HR Workflow Assessment Loop
+
+Iterative assessment for HR workflows registered in `registry/workflows/`.
+Feeds the INTENT phases: current-state assessment → automation roadmap → metrics
+framework → specific workflow refinement.
+
+## Purpose
+
+HR workflows in this repo are planning artifacts, not production automation.
+The assessment loop keeps each entry honest about what is known, what is
+automatable, and what must stay human-led—matching the INTENT balance of
+technology as amplifier, not replacement.
+
+## Loop stages
+
+Each workflow entry tracks `assessment.stage` in its front matter. Advance only
+when the exit criteria for the current stage are met.
+
+| Stage | Goal | Exit criteria |
+|-------|------|---------------|
+| `inventory` | Capture what exists today | Actors, triggers, inputs/outputs, and current tools documented |
+| `automation_potential` | Score routine vs strategic work | Automation candidates listed with impact/effort notes |
+| `human_touch` | Bound what stays human-led | Relational, ethical, or judgment-heavy steps explicitly retained |
+| `readiness` | Ready for roadmap prioritization | Dependencies, risks, and metrics hooks identified |
+
+Stages are linear for a first pass. Revisit earlier stages when org context,
+tools, or policy change.
+
+## Cadence
+
+- **On entry creation:** start at `inventory`.
+- **Per workplan cycle:** review open workflows; advance or document blockers.
+- **After INTENT phase shifts:** re-assess workflows tied to the active phase.
+
+## Outputs
+
+Stage progression produces inputs for downstream INTENT work:
+
+- `inventory` + `automation_potential` → **automation roadmap** prioritization
+- `human_touch` → policy drafts and manager-enablement notes
+- `readiness` → workplan tasks and (later) metrics framework hooks
+
+## Registry linkage
+
+- Workflow entries: `registry/workflows/*.md`
+- Index: `registry/indexes/workflows.yaml`
+- INTENT anchor: `INTENT.md` (phases and HR function list)
+- Scope boundary: `SCOPE.md`
+
+## Assessment record (per workflow)
+
+Workflow front matter includes:
+
+```yaml
+assessment:
+  stage: inventory | automation_potential | human_touch | readiness
+  last_reviewed: "YYYY-MM-DD"
+  blockers: []
+  notes: []
+```
+
+Update `last_reviewed` whenever the stage changes or material facts change.
