Observability driven development

" summary

Clear claim: add observability from day one so production bugs are debuggable. Concrete tools and practices: instrument a Flask todo app with new relic, emit structured logs with request id traceability and extras instead of interpolated text, use proper log levels, and prefer OpenTelemetry for vendor portability. Real numbers and fixes: a bulk update removes N per-item selects/updates, making an async log handler and a bulk save converts a 50-update hotspot into a fast path; one case processes 8 million messages a day and gains an 8× speedup.
