-- [ ] Create `packages/core-shared/src/security/security-types.ts` with `SecurityHeadersConfig` + `CspMode` types; implement `packages/core-shared/src/security/nonce.ts` with `generateNonce()` using `crypto.randomBytes`; implement `packages/core-shared/src/security/build-security-headers.ts` emitting all six headers with prod/dev CSP mode, nonce threading into `script-src`, `allowedConnectOrigins` / `allowedImgOrigins` / `allowedFontOrigins` applied to CSP, URL validation throwing `InvalidSecurityHeadersConfig` on malformed origins; unit tests covering header set, CSP variants, nonce threading, allowlist CSP directives, URL validation error, nonce randomness; export from `core-shared` barrel; all gates pass.
