Adam Moussa 8ed6268be2 feat(infra): build + pin the baked open-swe-base-arm64 AMI (T12 AMI / item 3)
Packer-build the custom base image and repoint AppService off the AL2023
placeholder onto it.

deploy/ami/open-swe-base.pkr.hcl — fix two bugs that blocked the first real
`packer build` (the config had only ever been `packer validate`'d at T8):
  - the file provisioner failed uploading the templates dir ('scp: …: Is a
    directory') — a trailing-slash contents-upload needs the dest dir to exist;
    added a 'mkdir -p /tmp/open-swe-templates' shell provisioner + dropped the
    dest trailing slash.
  - the shell provisioner's custom execute_command omitted {{ .Vars }}, so the
    environment_vars never reached provision.sh (which runs under set -u and
    aborted on CLOUDWATCH_AGENT_DEB_URL). Added {{ .Vars }}.

infra:
  - ami-cache.ts: BAKED_OPEN_SWE_AMI_ID = ami-0545363bb147229ff (built 2026-06-26
    from open-swe-base-arm64-20260626-201929) + bakedOpenSweArm64() pinning it by
    exact id via MachineImage.genericLinux (offline, deterministic). Dropped the
    now-dead AL2023 cachedInContext helper + context key; kept the EBS/replacement
    discipline docs.
  - app-service.ts: machineImage → bakedOpenSweArm64().
  - open-swe-stack.ts: output BakedAmiId (was the AL2023 PinnedAmiId guard).
  - cdk.context.json → {} (AMI is a static id pin; no context lookups remain).
  - README: Baked AMI + EBS-replacement-discipline section.

tsc + cdk synth(dev+prod) + jest(16) clean; template ImageId = the baked AMI.

NOTE: held — do NOT merge until the open-swe-dev secret values are populated
(put-config.sh). The infra CD is live, so merging this to dev auto-deploys
OpenSweDevStack; without secrets the box boots but fetch-config fail-fasts →
unhealthy ALB target on the shared prod ALB. Merge once secrets are set (T14).
