havm 0.3.0

What's new in v0.3.0

Runs on macOS 15 or later

The minimum deployment target drops from macOS 27 (Golden Gate) to
macOS 15 (Sequoia). All core functionality — EFI boot, bridge/NAT
networking, the interactive serial console, the SSH-key CONFIG disk,
graceful shutdown, and Prometheus metrics — works unchanged on
macOS 15 and 26.

USB accessory passthrough (the menu bar hot-attach of Zigbee
coordinators etc.) remains a macOS 27 feature: it depends on the
AccessoryAccess framework and VZUSBPassthroughDevice. On macOS 15–26,
havm run logs a message and continues without it. The CONFIG disk is
unaffected — SSH key import still works on every supported release.

New --log-level option

havm run --log-level {debug,info,warning,error} overrides
logging.level from the config file — handy for debugging a Homebrew
service without touching its config.

Reliability & diagnostics

• logging.level: error now maps to .error (previously mapped to
  .critical, which suppressed all output).
• An unexpected VM stop now exits with status 1, so launchd
  (brew services) reliably restarts the process.
• A warning is logged when the Home Assistant web UI doesn't respond
  within 5 minutes of the guest becoming reachable.
• Config hot-reload parse failures, PID file write/remove errors, MAC
  address regeneration, and console cmdline patch failures are now
  logged instead of failing silently.
• MemorySize parsing rejects values at the exact 2^64 boundary.

Dependencies

• swift-log 1.15.0
