# Smoke test: verify wrappers auto-init StackMemory and create context.db
#
# Steps:
#  - Create a fresh git repo
#  - Prepend a PATH shim so "stackmemory" resolves to local dist CLI
#  - Run each wrapper with flags to avoid external tool execution
#  - Assert .stackmemory/context.db is created (DB enabled)
#
# Notes:
#  - Requires that better-sqlite3 can load on this system.
#  - Unsets env that disables DB in CLI (STACKMEMORY_TEST_SKIP_DB).
