docs(core-shared): add glossary entries + update conformance refs for rate-limit and security headers

- Add IRateLimit, RateLimited, withRateLimit, SBOM, SecurityHeadersConfig,
  buildSecurityHeaders, nonce (CSP) entries to docs/glossary.md
- Bump conformance rule count 12 → 13 in CLAUDE.md; add rateLimit manifest
  field to description; add no-undeclared-rate-limit to rule list
- Add rateLimit manifest field row + no-undeclared-rate-limit (13th rule)
  to docs/guides/conformance-quickref.md

 **Rate-limit** (`core-shared/rate-limit`):
 Fourth conformance channel after audit/analytics/consent. `IRateLimit` interface (`consume`/`reset`) + `withRateLimit` wrapper + `RateLimited` brand + `rateLimit: { window, budget }` manifest field. Default budgets in manifest, runtime overrides via `ctx.rateLimit` config. Consumer wires Redis/Upstash impl. See ADR-025.
 
+**`IRateLimit`**:
+The vendor-neutral rate-limit interface in `@repo/core-shared/rate-limit/`. Two methods: `consume(budgetName, key, weight?)` → `RateLimitDecision` (fields: `allowed: boolean`, `remaining: number`, `resetAt: Date`) and `reset(budgetName, key)`. Two implementations: `InMemoryRateLimit` (dev/test) and a consumer-wired production backend (Redis/Upstash). Feature packages receive it via `ctx.rateLimit` at DI bind time; declared in the manifest's `rateLimit` field.
+
+**`RateLimited`**:
+The phantom-type brand `RateLimited<F>` attached by `withRateLimit(rateLimit, fn)` at DI bind time. Signals that the wrapped use case's declared `RateLimitBudget[]` entries will be enforced before execution. TypeScript rejects binding an unwrapped factory to a `RateLimited`-typed DI symbol when the manifest declares `rateLimit`. The boot assertion verifies the brand at runtime.
+_Avoid:_ applying `withRateLimit` in test files — tests inject mocks directly and do not go through the DI wrappers.
+
+**`withRateLimit`**:
+The wrapper composer that attaches the `RateLimited` brand at DI bind time. Signature: `withRateLimit(rateLimit: IRateLimit, fn)`. Part of the six-wrapper composition chain — see the combined `withSpan / withCapture / …` entry above. Outermost position is `withSpan`; `withRateLimit` sits between `withAnalytics` and the inner factory.

 **PII inventory**:
 Personal-data declaration at the Payload field level via `custom.pii = { category, purpose, retention, exportable, restrictable }`. Generator emits `compliance/data-map.yml`. DSR cascade walks this at runtime. See ADR-025.

+## Security
+
+**`SecurityHeadersConfig`**:
+The TypeScript type accepted by `buildSecurityHeaders()`. Fields: `mode` (`"prod"` | `"dev"`), optional `nonce` (per-request CSP nonce string), and optional allowlist arrays `allowedConnectOrigins`, `allowedImgOrigins`, `allowedFontOrigins` (absolute URLs). Lives at `@repo/core-shared/security`.
+
+**`buildSecurityHeaders()`**:
+The pure function in `@repo/core-shared/security` that accepts a `SecurityHeadersConfig` and returns a `Record<string, string>` of HTTP security headers: `Strict-Transport-Security`, `X-Frame-Options`, `X-Content-Type-Options`, `Referrer-Policy`, `Permissions-Policy`, and `Content-Security-Policy`. In `"prod"` mode the CSP uses `strict-dynamic` + nonce; in `"dev"` mode it relaxes to `unsafe-inline`/`unsafe-eval` to allow HMR tooling.
+
+**`nonce`** (CSP context):
+A per-request cryptographically random token (typically 16+ bytes, base64-encoded) threaded into the `Content-Security-Policy` header's `script-src` directive as `'nonce-<value>'`. Required when using `strict-dynamic` CSP to permit specific server-rendered inline `<script>` tags (e.g. Next.js bootstrap chunk, Sentry SDK loader) without `unsafe-inline`. Passed to `buildSecurityHeaders({ nonce })` and set as the `nonce` attribute on matching `<script>` elements.
+_Avoid:_ reusing the same nonce across requests — it must be regenerated per HTTP response to preserve the security guarantee.
