Convert AWS Lambda source

Convert AWS Lambda handler code to a Raff function. Stateless — nothing is stored; review the output, then create a function and deploy the returned files.

Two modes:

  • rewrite (default) — AI rewrites the handler to a portable standard handler (FastAPI / Web Fetch / net/http). Every guess is flagged in warnings. 5 free per calendar month, then $0.30 per conversion from your balance. Up to 64KB of source.
  • adapter — your code ships unchanged plus a small static shim that presents API-Gateway-style events. Instant, free, unlimited.

Config always maps deterministically: memory/timeout, env vars to raff_toml, EventBridge rate() schedules to cron trigger proposals. IAM, VPC, layers and stream sources are listed in out_of_scope with alternatives.
