v1.0.2

Hardening release. 1,836-test harness revealed and fixed: Motion Project Browser suppressed (no more modal on launch); command palette async dispatch (no more bridge hangs on modal-opening selectors); broad blocklist for state-dependent crashy selectors (editMarker, shareToDefaultDestination, etc); Lua VM now initializes on Motion; Lua string handling hardened against invalid UTF-8 and runaway loops; null action params rejected cleanly.
