Subject: [PATCH 1/2] feat: add --fail-on-warnings flag to check command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for the --fail-on-warnings flag that mirrors the behavior
of the underlying svelte-check CLI. When this flag is passed to the
check command:

- If running in daemon mode: exit with code 1 when hasWarnings is true
- If running svelte-check directly (fallback): pass --fail-on-warnings
  to svelte-check

This allows CI pipelines to fail on warnings, matching the behavior
users expect from svelte-check --fail-on-warnings.

Bumps version to 0.1.0.
