* feat(lambda): add SAM template and sample events for AWS deployment Phase 6.2 of the distributed rendering plan (DISTRIBUTED-RENDERING-PLAN.md §15). Reference SAM template for deploying HyperFrames distributed rendering on AWS — one Lambda function in three roles, choreographed by a Step Functions standard workflow with a Map state for parallel chunk rendering. Resources created by the template: - Lambda function pointing at the Phase 6.1 ZIP - Step Functions state machine: Plan -> Map(N) RenderChunk -> Assemble - S3 bucket for plan tarballs, chunk outputs, final mp4 - IAM role for the state machine - CloudWatch alarm guarding against runaway chunk invocations Retry policy: 4 attempts, 2s initial, 2x backoff, max 60s, with the typed non-retryable error codes from plan §9.3 explicitly opted out. CodeUri points at packages/aws-lambda/dist/handler.zip; sam deploy resolves the local path and uploads to a SAM-managed bucket on first deploy. Validated: sam validate --lint passes against the template. This is part of the 8-PR Phase 6 stack; PR 6.2 of 8. * fix(lambda): address PR 879 review feedback - Add CloudWatch alarms for Lambda Errors metric (5min window, threshold 1) and Step Functions ExecutionsFailed metric. The existing runaway- invocations alarm catches too-many-calls but missed silent per-chunk failures and retry-exhaustion. - Document VersioningConfiguration: Suspended tradeoff inline. Adopters treating the final mp4 as user-keepable should bump to Enabled. - Cost-allocation Tags on RenderBucket + Lambda Globals. - Lambda Tracing: Active so X-Ray spans don't terminate at the SF→Lambda boundary (the state machine already had tracing). - State-machine top-level TimeoutSeconds: 3600 as defensive ceiling on the whole choreography — catches Plan-retry storms before they hit individual task budgets. - AssertChunkCount Choice state: if Plan ever returns ChunkCount=0 the Map would silently iterate zero times and Assemble would receive an empty ChunkS3Uris[] producing an empty output. Fail-fast with typed PLAN_TOO_LARGE error instead. - Architecture comment: explicit x86_64-only constraint from @sparticuz/chromium so adopters trying Graviton don't get bitten. * docs(lambda): drop internal plan-doc refs from SAM example + template
