fix(utils): restore optional logging peer deps

Bugbot flagged (and reproduction confirmed) that dropping the optional
peer deps broke GCP logger init at runtime. `await import()` in
utils/logging.ts resolves from utils' own module path, and pnpm's
isolated linker only links a transitive dep into utils/node_modules if
utils itself declares it. Without the peer, `ERR_MODULE_NOT_FOUND` is
swallowed by the try/catch and services silently log without GCP
structured fields.

Restoring the optional peers re-links the packages into utils'
node_modules when a consumer declares them directly. No API churn,
both the GCP and pino-pretty regressions are addressed.

-Added `@hyperlane-xyz/sdk` subpath exports for `core`, `hook`, and `ism` modules, and stopped advertising service-only logging peers from the root `@hyperlane-xyz/utils` package.
+Added `@hyperlane-xyz/sdk` subpath exports for `core`, `hook`, and `ism` modules. Hardened `@hyperlane-xyz/utils` pretty-mode logging with a graceful fallback when `pino-pretty` is not installed.
