Timezone-aware clock for Hermes.

Provides a single ``now()`` helper that returns a timezone-aware datetime
based on the user's configured IANA timezone (e.g. ``Asia/Kolkata``).

Resolution order:
  1. ``HERMES_TIMEZONE`` environment variable
  2. ``timezone`` key in ``~/.hermes/config.yaml``
  3. Falls back to the server's local time (``datetime.now().astimezone()``)

Invalid timezone values log a warning and fall back safely — Hermes never
crashes due to a bad timezone string.
