feat(webui): read-only workflow policy & guardrail visibility (Closes #646)

Phase 3 child of the Web Console epic #631. Operators can now see the active
workflow policy/guardrail configuration from the console instead of reading the
repo tree.

- webui/policy_inventory.py (new): redacted, machine-readable guardrail
  inventory. One row per major guardrail (role separation/RBAC, lease rules,
  worktree binding, merge confirmation, redaction, contamination, allocator
  policy, audit logging, mutation gating) with source pointers (file/module/doc)
  and a compact active projection from the existing safe policy accessors.
  Fail-soft per entry; whole payload run through console_redaction before emit;
  diff vs documented default where feasible.
- webui/policy_views.py (new): HTML cards with source pointers, active config,
  and the documented-default diff; read-only page copy, no forms.
- webui/app.py: register GET /policy and GET /api/v1/policy (additive).
- webui/layout.py: add Policy nav item.
- tests/test_webui_policy_visibility.py (new): guardrail presence + source
  pointers (AC1), redaction incl. planted-secret masking and scan_for_secrets
  (AC2/AC3), read-only page + no-mutation routes (AC4), fail-soft rendering.
- docs/webui-local-dev.md: route table + read-only policy-visibility section.

Read-only throughout; no policy editing, no gate-weakening toggle, secrets
redacted.

+## Policy & guardrail visibility (#646)
+
+`/policy` (HTML) and `/api/v1/policy` (JSON) surface a **read-only** projection
+of the major workflow guardrails — role separation/RBAC, lease lifecycle,
+author worktree binding, merge confirmation, secret redaction, contamination
+containment, allocator policy, audit logging, and mutation gating. Each entry
+carries source pointers to the file/module/doc that owns it, a compact active
+value derived from the existing safe policy accessors, and — where a documented
+default is declared — a diff of active vs documented. The whole payload is run
+through the console redaction pass before it is emitted, so a planted or
+accidental secret degrades to the placeholder rather than reaching a client.
+The view never edits policy and exposes no gate-weakening toggle.
+
 ## Deployment boundary (#435)
 
 MVP serves on loopback by default. Binding `0.0.0.0` or `::` is **refused**

-Regression coverage for the controller→required-role consume path:
-
-* controller allocates author work; independent author adopts successfully
-* author adoption succeeds after allocating controller process exits
-* author adoption without sharing controller session identity
-* wrong-role adoption rejected
-* concurrent/second adoption rejected without state corruption
-* terminal allocation adoption rejected
-* successful adoption produces authoritative ownership evidence
-* genuine abandoned-lease recovery remains valid
-* process_work_queue / allocate results include consume identifiers

+"""Read-only workflow policy and guardrail inventory for the web UI (#646).
+
+Policy and guardrails live in code, profiles, docs, and skills. An operator
+cannot *see* the active workflow policy configuration from the console without
+reading the repository tree. This module projects the major guardrails into a
+redacted, machine-readable inventory with source attribution (file / module /
+doc), so the console can render them as HTML tables with source pointers.
+
+Design constraints (Phase 3, #646):
+
+- **Read-only projection.** Nothing here edits policy or exposes a toggle that
+  could weaken a gate. It reports what is already enforced elsewhere.
+- **Source attribution without secrets.** Every guardrail carries pointers to
+  the file/module/doc that owns it. Live values are compact summaries derived
+  from the safe policy accessors that already exist (``rbac_matrix``,
+  ``redaction_policy``, ``audit_policy``); raw regex, tokens, and endpoints are
+  never embedded.
+- **Redact before emit.** ``snapshot_to_dict`` runs the whole payload through
+  ``console_redaction.redact_payload`` so a planted or accidental secret in any
+  projected value degrades to the placeholder rather than reaching a client.
+- **Fail soft.** A projection that raises is recorded as a per-entry error and
+  never takes the page down; a guardrail is still listed with its sources.
+- **Diff vs documented defaults where feasible.** When a guardrail declares a
+  documented invariant, the active projection is compared against it and the
+  result is reported; otherwise the diff is explicitly ``None`` with a reason.
