feat: promote audience_sync storyboard to canonical definitions (#2003)

* feat: promote audience_sync storyboard to canonical definitions

Full audience lifecycle storyboard: account discovery, audience creation
with hashed identifiers, and audience deletion via sync_audiences.

Fixes schema_ref paths (media-buy/ not audience/) and doc_ref paths
from the @adcp/client version. Adds track, required_tools, and
platform_types fields for client consumption.

26 canonical protocol storyboards total.

* fix: correct narrative — account must already exist, no sync_accounts fallback

* fix: add audio_platform to audience_sync platform_types

Streaming audio platforms (Spotify, Pandora) have user-level audience
data and support audience sync.

+  You support audience syncing via the sync_audiences task. Buyers push first-party
+  audience segments to your platform using hashed identifiers (emails, phones). Your
+  platform matches those identifiers against your user graph and returns match rates.
+
+  This storyboard verifies the full audience lifecycle: discover an account to sync
+  against, create a test audience with hashed identifiers, and clean up by deleting it.
