T8: compose.cloud.yml — multi-tenant cloud stack on port 8505, CLOUD_MODE=true,
per-user encrypted data at /devl/menagerie-data, joins caddy-proxy_caddy-internal
network; .env.example extended with five cloud-only env vars.
T10: app/telemetry.py — log_usage_event() is the ONLY entry point to usage_events
table; hard kill switch (all_disabled) checked before any DB write; complete no-op
in local mode; swallows all exceptions so telemetry never crashes the app;
psycopg2-binary added to requirements.txt. Event calls wired into 4_Apply.py at
cover_letter_generated and job_applied. 5 tests, 413/413 total passing.
