Release v2.1.0

[2.1.0] - 2026-07-15

Changed

• Invoke-AzCmd: the string -Arguments form now throws when the value contains a quote character — it splits on whitespace with no quote handling, so --name "my rg" silently became broken tokens and an opaque az error. Use -ArgumentList for values with spaces
• Invoke-AdeBicepDeployment: deployment polling now backs off with age (5s for the first 2 minutes, 15s until 10 minutes, then 30s) — long modules (AKS, APIM, gateways) previously generated thousands of ARM reads per deploy and risked 429 throttling
• deploy.ps1: the jobSchedule GUID is derived with SHA-256 (truncated) instead of MD5 — purely a scanner-noise fix; idempotency is name-based and unaffected, existing schedule links are still detected

Documentation

• README.md halved (942 -> 443 lines): nine reference-heavy sections moved verbatim to docs/reference.md (feature flags, parameters, custom profiles, scripts, repository structure) and docs/operations.md (seed data, auto start/stop, cost dashboard, GitHub Actions setup). All README headings and anchors unchanged; each section keeps a summary plus a link
