v0.2.0-beta.57f3d402

Second pre-release. darwin/arm64, ad-hoc signed with the
com.apple.security.virtualization entitlement (asserted in CI).

Changes since 0.1.0-beta

• fix(guest): the darwin runner now launches with a full login PATH
  (path_helper + Homebrew), so job steps find tools installed into
  /usr/local/bin — fixes aws: command not found immediately after a
  successful install.
• feat(home): per-pool guest CPU/RAM sizing (cpu_cores, ram_gb);
  zero/omitted keeps the image's baked values.
• feat(home)!: the runner-name prefix is now derived
  (<slug(hostname)>-<rand8>, persisted in ~/.runny/instance-id), not
  configured. BREAKING: the top-level name_prefix config key is removed;
  a config that sets it now fails to parse.

Install / upgrade

brew upgrade bojanrajkovic/tap/runny   # or: brew install bojanrajkovic/tap/runny

Then runnyd -doctor, and start as a LaunchAgent from a GUI login:
brew services start runny. See the setup gist for config + walkthrough.
