Hephaestus v1.0.2

Antigravity workflow surface fixed

The Antigravity global workflows (/hep-network, /hep-cloud, /hep-search, /hep-call, /hep-upload) were the only runtime adapter shipping without YAML frontmatter and with a prose-only recipe instead of a runnable command block. The host model had no deterministic command to execute and would improvise — fabricating PATH/git "fixes" instead of routing.

Each now carries a description and the same resolve-runner → route --runtime antigravity block the other runtimes use, plus explicit guardrails against inventing PATH/zshrc/git work. Mirrored to .agents/workflows/.

v1.0.x now published as a real release

v1.0.0/v1.0.1 existed only as git tags, so hephaestus update (which reads releases/latest) resolved to the stale v0.7.32. Publishing v1.0.2 as the latest release makes hephaestus update and install-all-runtimes.sh land on the current line on every machine.

Existing installs: run hephaestus update. Fresh installs pick up v1.0.2 automatically.
