v2.1.0

ATC 2.1.0 adds host integrations and fixes device policy and snapshot handling.

Host integrations and command guards

• Support GitHub Copilot CLI and app plugin hooks and MCP. Thanks to @prof18 in #5.
• Add Antigravity plugin support. See #7.
• Apply fail-closed command guards only to standalone tool words. Thanks to @prof18 in #6.

Device policy and snapshots

• Enforce allowPhysicalDevices and allowedPhysicalSerials during atc claim for Android and iOS. The policy defaults to "never"; it also accepts "explicit" and "always". Disallowed claims return exit code 6 (EPHYSICAL_FORBIDDEN) with guidance. atc config set validates policy values.
• Prefer offline Android Virtual Devices whose system image exists on disk over candidates with missing images.
• Detect KO: errors on stdout from adb emu avd snapshot, even when adb exits with code 0.
• Exclude TCC-protected Simulator caches (Library/Spotlight and Library/Caches/locationd) during APFS snapshot save and load on macOS Sequoia. This lets atc snapshot run in terminals without Full Disk Access.

Contributors

• @prof18 made their first contribution in #5.
