feat(advisory-ai): Add deployment guide, Dockerfile, and Helm chart for on-prem packaging

- Introduced a comprehensive deployment guide for AdvisoryAI, detailing local builds, remote inference toggles, and scaling guidance.
- Created a multi-role Dockerfile for building WebService and Worker images.
- Added a docker-compose file for local and offline deployment.
- Implemented a Helm chart for Kubernetes deployment with persistence and remote inference options.
- Established a new API endpoint `/advisories/summary` for deterministic summaries of observations and linksets.
- Introduced a JSON schema for risk profiles and a validator to ensure compliance with the schema.
- Added unit tests for the risk profile validator to ensure functionality and error handling.

+# `/advisories/summary` API (draft v1)
+
+Status: draft; aligns with LNM v1 (frozen 2025-11-17) and observation/linkset models already shipped in Concelier Core.
+
+## Intent
+- Provide graph overlays and consoles a deterministic summary of observations and linksets without derived verdicts.
+- Preserve provenance and tenant isolation; results are stable for a given tenant + filter set.
+
+## Request
+- Method: `GET`
+- Path: `/advisories/summary`
+- Headers:
+  - `X-Stella-Tenant`: required.
+  - `X-Stella-Request-Id`: optional for tracing.
+- Query parameters:
+  - `purl` (optional, repeatable) — filter by component coordinates.
+  - `alias` (optional, repeatable) — advisory aliases (CVE, GHSA, vendor IDs); case-insensitive; normalized and sorted server-side.
+  - `source` (optional, repeatable) — upstream source identifiers.
+  - `confidence_gte` (optional, decimal 0–1) — minimum linkset confidence.
+  - `conflicts_only` (optional, bool) — when `true`, return only summaries with conflicts present.
+  - `after` (optional, cursor) — opaque, tenant-scoped cursor for pagination.
+  - `take` (optional, int, default 100, max 500) — page size.
+  - `sort` (optional, enum: `advisory`, `observedAt`, default `advisory`) — always ascending and stable.
+
+## Response (200)
+```json
+{
+  "meta": {
+    "tenant": "acme",
+    "count": 2,
+    "next": "opaque-cursor-or-null",
+    "sort": "advisory"
+  },
+  "items": [
+    {
+      "advisoryKey": "cve-2024-1234",
+      "aliases": ["GHSA-xxxx-yyyy", "CVE-2024-1234"],
+      "source": "nvd",
+      "observedAt": "2025-11-22T15:04:05Z",
+      "linksetId": "ls_01H9A8...",
+      "confidence": 0.82,
+      "conflicts": [
+        { "field": "severity", "codes": ["severity-mismatch"], "sources": ["nvd", "vendor"] }
+      ],
+      "counts": {
+        "observations": 3,
+        "conflictFields": 1
+      },
+      "provenance": {
+        "observationIds": ["obs_01H9...", "obs_01H9..."],
+        "schema": "lnm-1.0"
+      }
+    }
+  ]
+}
+```
+- Ordering: stable by `sort` then `advisoryKey` then `linksetId`.
+- No derived verdicts or merged severity values; conflicts are emitted as structured markers only.
+
+## Errors
+- `400` `ERR_AOC_001`: missing/invalid tenant or unsupported filter.
+- `400` `ERR_AOC_006`: `take` exceeds max or invalid cursor.
+- `401/403`: auth/tenant scope failures.
+- `429`: if per-tenant rate limits enforced (surface retry headers).
+
+## Determinism & caching
+- Response depends solely on tenant + normalized filters + underlying linksets; no clock-based variation beyond `observedAt` from stored records.
+- Cache key (for optional summary cache):
+  - `tenant|purls(sorted)|aliases(sorted)|sources(sorted)|confidence_gte|conflicts_only|sort|take|after`
+  - Return transparency headers: `X-Stella-Cache-Key` (sha256-16), `X-Stella-Cache-Hit`, `X-Stella-Cache-Ttl`.
+  - Cache TTL should default to 0 (disabled) until validated; determinism required for hits.
+
+## Notes
+- Cursor must encode the final sort tuple (`advisoryKey`, `linksetId`, `observedAt`) to keep pagination stable when new data arrives.
+- All string comparisons for filters are case-insensitive; server normalizes to lower-case and sorts before query execution.
+- Conflicts mirror LNM conflict codes already produced by Core (no new codes introduced here).
