v0.5.1

Relay 0.5.1 release notes

This is the first published release. No GitHub release existed before, so
everything documented for 0.5.0 — automatic cleanup, Linux/macOS installers,
relay add-agent, the English --help overhaul — ships here as well.

It is also the first release built automatically and verified on Windows,
macOS, and Linux.

Fixed

• A fresh clone could not be installed: the installers expected relay.pyz to
  be in the repository. They now build it when it is missing.
• 9 of 60 tests failed on Windows, because the test fixtures always invoked the
  POSIX mock CLIs. The suite now selects the .cmd wrappers on Windows.
• The Windows mock wrappers all reported themselves as claude, which
  invalidated worker-fallback and doctor --deep results on Windows.
• SHA256SUMS.txt was maintained by hand and had gone stale. It is now
  generated together with relay.pyz, so the two cannot disagree.

Added

• CI: every push and pull request runs the full suite on Windows, macOS, and
  Linux across Python 3.11–3.13.
• Automated releases: pushing a v* tag verifies, tests, builds, and
  publishes. Any check failing stops the run before the release is created.
• workers.claude.permission_mode is now configurable. The default is
  unchanged (bypassPermissions).
• relay doctor warns when a worker bypasses permission checks and no
  OS-level isolation has been recorded. Advisory only.
• SECURITY.md, CODEOWNERS, Dependabot, issue labels, and ruff linting.
  Development tooling only — Relay still has zero runtime dependencies.

Changed

• relay.pyz and SHA256SUMS.txt are no longer tracked in the repository.
  They are published only as release assets.

Verification

66 tests pass on Windows, macOS, and Linux across Python 3.11–3.13.

Provider CLI behavior still requires relay doctor --worker <worker> --deep on
each target machine, and again whenever the underlying CLI is upgraded.
