v0.2.4 - MapEnhancer version detection

Probe for version-specific types at startup to determine which MapEnhancer
build is installed, then gray out features unavailable in that build.

Three tiers: official v1.5.2 (minimal), v1.6.0 (adds turntable markers),
and the community fork (full feature set). Detection uses type probes -
TurntableHelper for the v1.6.0+ tier, SwitchResetAuditState for community.

Adds HasTurntable and IsCommunity capability flags on MapEnhancerBridge,
imMEHasTurntable/imMECommunity atomics on PopoutWindow, and a two-arg
RRPOPOUT_SetMapEnhancerCaps export. The renderer reads both flags and wraps
community-only menu items in BeginDisabled blocks accordingly.

Updates README with version compatibility notes and comparison screenshots.

 ### MapEnhancer Integration
 
-If [MapEnhancer](https://github.com/Refizar08/rr-mapenhancer-fix) is installed, the toolbar gear menu expands with follow controls and a settings panel. The **Follow** submenu lets you follow the player camera, the selected locomotive, or any consist picked from a live-updated list. **Jump to Location** is also available. The **Settings** panel gives you live control over all MapEnhancer rendering options without leaving the map: marker visibility toggles, scale sliders for flares, junctions, track lines, and crossings, and bulk switch reset buttons.

+Both the original official builds and the [community fork](https://github.com/Refizar08/rr-mapenhancer-fix) are supported. Features added by the community fork - turntable control, road crossing markers, passenger stop tracking, industry area colors, modded spawn points, and bulk switch reset - are grayed out when an older build is detected. All controls that the installed version supports remain fully functional.
