Slack/Discord notifier for scan history digests

[mesrikanthreddy]

Why

Teams running KShield across multiple repos/machines have no shared visibility into what's being caught or suppressed — everything lives in each developer's local SQLite history. A periodic digest posted to Slack/Discord (via webhook) would give a team-level view without standing up shared infrastructure.

Proposed scope

• Small standalone script/cron (or optional backend background task) that:
  • Reads recent scans via the existing GET /api/v1/scans history endpoint.
  • Formats a digest (new findings, suppressed count, critical/high highlights) and posts to a configured Slack or Discord webhook URL.
• Config via env var (webhook URL, digest frequency) — no new backend endpoints needed since /api/v1/scans already returns what's required.

Priority note

Lowest priority of the five — nice-to-have, not a driver of adoption. Reasonable to pick up opportunistically or leave for community contribution.
