feat: v0.19.0 — debug-observability core complete

Milestone minor (operator-approved). Publishes the design-brief's
headline deliverable: the multi-pane debug-observability dashboard is
complete — all four observability panes are built and consuming their
real Worldtree endpoints:

- Persona      → GET /agents/{id}/persona_state
- Tools        → GET /sessions/{id}/tools
- BifrostState → GET /admin/sessions/{id}/bifrost
- AdminEvents  → GET /admin/events (SSE)

v1 client-REST coverage is 12/40; both non-REST surfaces (SSE 11/11,
Bifrost provider planes 8/8) already complete. Only Tier-2 client I/O
(transient-characters routing, persona_state-write) remains in scope;
everything else is covered or excluded-by-design in docs/coverage-map.md.

Version bump only (the feature arc landed across v0.18.5–v0.18.11).

+## Amendment 2026-07-01 — admin BifrostState read (v1 coverage-audit)
+
+Admin-scoped Bifrost dispatch-state read (spec #176, `GET /admin/sessions/{id}/bifrost`),
+surfaced in the TUI BifrostState pane on session-attach. The first admin-key
+consumer in ratatoskr: requires the `admin.sessions.read` scope, so the request
+OVERRIDES the Authorization header with the caller-supplied `admin_key` (distinct
+from the client's default consumer key). Same result-shape convention as the
+other introspection wrappers: 200 → parsed dict verbatim, non-200 → `SessionApiFailed`.

+BRIEF: GET /admin/sessions/{session_id}/bifrost — admin-scoped live Bifrost binding (spec #176): {endpoint_url, consumer_id, connected, capabilities_granted, tools:[{name, description}]}. Requires admin.sessions.read; the request sets Authorization: Bearer <admin_key> (override), NOT the client's default consumer bearer. Parsed dict verbatim; any non-200 → SessionApiFailed — notably 403 auth_scope_denied and 404 session_not_bifrost_bound.
