# Reset FlintTrade user state for a fresh-install test.
#
# Wipes the
# per-OS workspace directory (auth.db, credentials.db, activity, security,
# traffic/error logs, jwt_secret, master_password, workspace.json,
# contracts cache, rag store):
#   Linux   ~/.flinttrade
#   macOS   ~/Library/Application Support/flinttrade
#   Windows %APPDATA%\flinttrade
# Overrides, in precedence order: FLINTTRADE_WORKSPACE_DIR > FLINTTRADE_HOME.
# Either may be written with a leading '~' or relative; both are expanded and
# made absolute exactly as flinttrade_core.workspace resolves them.
#
# Archives everything first to .local/archive/flinttrade-state-<ts>/
# per the project's never-delete rule. Nothing is lost, just moved.
#
# Usage:
#   scripts/reset-flinttrade-state.sh           # archive + wipe + (user restarts backend)
#   scripts/reset-flinttrade-state.sh --restart # also kill + restart backend
