Add "disable_web_page_preview": True to the JSON payload of both
low-level Telegram primitives — send_telegram (POST /sendMessage) and
edit_telegram (POST /editMessageText). Telegram no longer expands the
Plane "Modern project management" link-preview banner under every
tracker card (bump/edit) and notify/alert message, which the default
bump mode (ORCH-067) was duplicating on each transition.
Single-point fix at the primitive level — all consumers
(update_task_tracker, notify_approve_requested, notify_error, stage
alerts from launcher/stage_engine) inherit it without code changes.
parse_mode: HTML is preserved so the ORCH-NNN issue link stays
clickable; disable_notification, bump/edit logic, the one-card-per-task
invariant, return contracts and never-raise are untouched. Unconditional,
no kill-switch (ADR-001).
Tests: tests/test_link_preview_disabled.py (TC-01..06). Docs: CHANGELOG,
CLAUDE.md, docs/architecture/README.md (Notifications component).
