Merge pull request #486 from pimaster900/docs/message-pipeline #35

	# Issue #388 — Security regression checks.
	#
	# Runs on every PR and push to main. Two jobs:
	# - regression: the ciphertext-only guard and the private-key/session-state
	# field scan (apps/backend/src/__tests__/security.regression.test.ts).
	# - dependency-audit: `pnpm audit` scoped to the crypto-relevant backend
	# dependencies (ioredis, jsonwebtoken, web-push, @stellar/stellar-sdk,
	# drizzle-orm, socket.io), surfacing CVEs without failing on advisories
	# in unrelated transitive deps.
