"""ORCH-080 — suppress Telegram link-preview in tracker/notify primitives.

Both low-level primitives ``send_telegram`` (POST /sendMessage) and
``edit_telegram`` (POST /editMessageText) must add
``"disable_web_page_preview": True`` to their JSON payload, so the Plane
"Modern project management" banner no longer expands under every tracker card /
notification. The clickable issue link must stay clickable -> ``parse_mode:
"HTML"`` is preserved in both payloads, and the never-raise / return contracts
are unchanged.

Network is isolated: ``src.notifications.httpx`` is patched; creds are stubbed.
Test ids TC-01..TC-06 from 04-test-plan.yaml.
