Combine Workshop addon and fix prison startup

Merge owned systems into one addon while preserving resource identities. Gate player admission on the replicated prison scene, restore the original framed door, and hold enemy AI until escape. Correct scenario branding and author metadata, include publishing assets, and retain regression and native verification evidence.

 # Current development status
 
+Current source now uses one combined addon. Open `addons/core/addon.gproj` and
+`Missions/ERR_Everon.conf`; see [single-mod migration](single-mod.md). The older
+five-addon checkpoints below retain their original scope and do not qualify the
+merged source.
+The merged Workbench HQ-memory run completes 101 assertions with no script/runtime
+failures; all 191 offline regression programs pass. Four existing external
+localization resource errors remain in the strict native verdict.

 **20 September 2026 — report-driven road interception:** HQ can now use fresh delivered movement history to select a forward point on an authored road and order an existing infantry group to hold it temporarily. The bounded selector respects reserved destinations, physical clearance and elevated-road geometry; old or weak evidence falls back to search. Existing radio delivery, force limits, home guards and absolute task expiry remain in charge. No barricades, vehicles, mines or new troops are created. [Implementation and scope](road-interception.md).
 
 All repository checks pass. The [native113607 raw checkpoint](evidence/native-2026-09-20-113607-road-interception-raw/README.md) completes101 assertions/one round with zero script/runtime failures, including an actual Everon road selection and stale-belief refusal from arranged private-memory reports. Four external localization errors remain. A process-exit race prevented the runner's final cleanup seal; its failed verdict is retained. A later independent read-only check found the reported PID absent, the private prefix idle and source bytes unchanged. This is not infantry-arrival, natural-interception, multiplayer or FPS evidence. The [refreshed development handoff](../.build/playtest-2026-09-20-road-interception/README.md) now contains all five packages and matching editable source:261 authored files,222 exact PAK payload entries and15 verified runtime files. [Packed Core](evidence/packed-core-2026-09-20-road-interception/report.json) starts cleanly. [Full external startup](evidence/raw-packed-chat-external-2026-09-20-road-interception/README.md) verifies the13-addon paths, ordinary modules, mission header and local prisoner admission without script/runtime failures, but remains failed on four external localization errors appearing twice. Both packed runs confirm unchanged inputs and hidden/muted cleanup. [Build/handoff record](evidence/package-2026-09-20-road-interception/handoff.json). All533 reference sources are unchanged; previous handoffs remain intact. Native packaging shutdown failures, full human escape, multiplayer and FPS acceptance remain unqualified.
