fix: graceful TPM fallback in VM creation, fix vm_destroy cleanup
vm_create() now handles swtpm initialization gracefully: - Pre-initializes swtpm state dir if /var/lib/libvirt/swtpm/ is writable - Falls back to VM without TPM if swtpm setup fails (with clear warnings) - Uses PID-suffixed paths for disk and ISO to avoid stale file conflicts - Removed unused VM_DISK_PATH/VM_ISO_PATH globals (now local vars) vm_destroy() cleanup: - No longer references undefined local variables from vm_create - Uses glob patterns to clean all VM files in /tmp/ - Explicitly preserves ISO in output/ Template changes: - TPM is now @TPM_SECTION@ placeholder (injected based on swtpm availability) - Allows same template to work with or without TPM AGENTS.md additions: - VM testing & swtpm setup documentation - Direct QEMU alternative when libvirt has issues - Session lessons: never delete ISO, never remove TPM, always test E2E All 523 unit tests pass, 0 lint warnings. 💘 Generated with Crush Assisted-by: GLM-5.1 via Crush <crush@charm.land>
