RMBC Skills Upgrade

Two modes: inline (called by preambles when UPGRADE_AVAILABLE detected) and standalone (/rmbc-upgrade).

Variable convention: OLD_VER and NEW_VER refer to version strings parsed from preamble output (e.g., from UPGRADE_AVAILABLE 1.0.1 1.1.0, OLD_VER=1.0.1 and NEW_VER=1.1.0). CUR_VER refers to the currently installed version from $_RMBC_ROOT/VERSION.

Inline Upgrade Flow

Called by other skills when preamble output contains UPGRADE_AVAILABLE <old> <new>. Parse the two version strings into OLD_VER and NEW_VER.

Step 1: Check auto-upgrade config

source "$_RMBC_ROOT/lib/rmbc-common.sh"
_AUTO=$(rmbc_config_get auto_upgrade)
echo "AUTO_UPGRADE: ${_AUTO:-false}"

If AUTO_UPGRADE is true: skip to Step 2 immediately.
