Implement a new stats module for the Telegram bot that tracks per-command usage with persistent KV storage. The module provides a /stats command displaying usage sorted by popularity with a 4096-byte Telegram message cap. Includes CommandHook integration for post-dispatch tracking via background goroutine (2s bounded context), proper test coverage, and registry initialization. Updated server config with stats factory and reserved concurrent execution control to prevent TOCTOU issues.
miti99bot
Plug-n-play Telegram bot framework in Go. Runs on AWS Lambda + DynamoDB + EventBridge Scheduler. Strictly free-tier.

End-to-end smoke test against a Telegram dev bot needs ngrok (local) or a deployed Function URL. The dev bot is created manually; token injected via env vars only.
For DynamoDB integration tests:
make dynamodb-local # docker run amazon/dynamodb-local on :8001
make test-dynamodb # runs internal/storage tests against DDB Local
Test
make vet # go vet
make test # full unit suite (no emulator)
make test-dynamodb # storage tests against DynamoDB Local (requires Docker)
Deploy
First-time onboarding: see docs/deploy-aws-free-tier-guide.md.
Steady-state operations: docs/deploy-aws.md.
After the initial setup, every push to main triggers .github/workflows/deploy.yml (GitHub Actions OIDC → SAM deploy). No long-lived AWS keys.
