P2: The blaxel entry in web/services/vms/images/manifest.json still records the r7 bake (agentToolResolvedVersions 2.1.246/0.150.0/1.18.23/0.84.3/0.35.1, builderScriptVersion cmux-devbox-2026-08-27-r7), but this PR bakes r12 with the new pins and the PR description says the image was already baked and live-verified. build-blaxel-image.sh's documented workflow is to update the manifest after a successful bake, so the default blaxel image record is now stale. Update the blaxel entry (version, builtAt, builderScriptVersion, agentToolResolvedVersions, notes) to the r12 bake in this PR.

Regenerate the Blaxel image manifest for this epoch.

The Blaxel build script requires a manifest update after each bake. manifest.json still records the prior agent pins and r7 validation metadata, while the Dockerfile builds epoch 2026-08-31-r12 with newer pins. Add the new validated entry before publication.

In `@web/services/vms/images/blaxel/Dockerfile` at line 25, Update the Blaxel
image manifest to add the validated entry for epoch 2026-08-31-r12, including
the newer agent pins and corresponding validation metadata, so it matches the
Dockerfile’s CMUX_IMAGE_EPOCH before publication.

P3: The blaxel and devbox images claim lockstep parity, but this bump now ships devbox with older coding-agent and cua-driver versions (2.1.246/0.150.0/1.18.23/0.84.3/0.35.1 and cua 0.19.3). This is tracked as a follow-up, but the drift contradicts the 'keep in lockstep' contract in devbox/Dockerfile, so confirm the follow-up is actually scheduled or apply the same bump to devbox.
