 * @module @arcis/node/core/patterns-loader
 *
 * Loads the shared security regex patterns from the bundled
 * `data/patterns.json` (a copy of the canonical `packages/core/patterns.json`,
 * kept byte-identical by the CI data-sync-check). This is the Node counterpart
 * of Go's `sanitizers/loader.go` and Python's `core/constants.load_patterns` +
 * `_compile_rules`.
 *
 * Why this exists: pre-migration, Node hardcoded every regex in `constants.ts`,
 * so each pattern edit was a manual dual-write against patterns.json (which
 * Python + Go already load at runtime). That is a Pattern 2 violation
 * (Shared Pattern Repository). Sourcing the arrays from patterns.json here
 * makes patterns.json the single source for all three SDKs.
 *
 * The JSON is a static `import`, so tsup inlines it into the CJS + ESM bundles
 * at build time (same as `bot-detection.ts` does with `bot-patterns.json`); no
 * runtime filesystem access. resolveJsonModule is already enabled in tsconfig.
