Consolidate the suite into one installable Institution mod with toggles

This repo is now the single player-facing mod. It bundles the whole engine and
all three feature layers into one folder -- Core, Contraband, Justice, and Gangs
DLLs plus Contraband's Defs -- with one About.xml and a settings shim that turns
each layer on or off from a checkbox (all on by default). A player installs one
mod (this) and Harmony; no separate Core dependency.

- Source/Institution: the only new code, a settings shim (InstitutionMod +
  InstitutionModSettings) that writes the player's choices into Core's shared
  InstitutionSettings. It owns no gameplay.
- Tools/package.sh: rebuilds the sibling DLLs clean and vendors them + Contraband's
  content in here, so the repo stays a complete drop-in.
- Assemblies/, Defs/, Textures/, Languages/: the vendored, assembled mod.

Still fully modular and splittable: the feature code stays in its own repos and
DLLs (their About.xml files remain), so breaking this back into separate mods is
just shipping them individually -- no code change.

+# Assemble the shippable, drop-in "Institution" mod into this repo.
+#
+# The Institution suite's code lives in SEPARATE sibling repos (rimworld-core, -contraband, -justice,
+# -gangs) as independent projects/DLLs -- that is what keeps it modular and splittable. For DISTRIBUTION
+# they are vendored into ONE mod folder (this repo) with one About.xml and a settings shim that toggles
+# each layer. This script rebuilds the sibling DLLs clean (no self-test) and copies them + Contraband's
+# Defs in here, so the repo is a complete installable mod.
+#
+# To split back into separate mods later: stop running this, and ship each sibling repo as its own mod
+# (their About.xml files still exist). Nothing in the code changes.
+#
+# Usage:  Tools/package.sh          (assumes siblings at ../rimworld-<name>)
