Improve launcher injection and hook reliability

Find Fabric through the render thread's class loader and make bytecode transformations safer for launcher-provided class definitions. Improve hook reporting, process-picker refresh behavior, and self-destruct cleanup; document Dawn and Lunar 1.21.11 setup.

+### Dawn and Lunar Client 1.21.11
+
+Use a 1.21.11 Fabric profile in Dawn or enable Lunar Client's Fabric add-on for 1.21.11. The target
+profile needs Fabric Loader 0.19.x and Fabric API. Wait for the title screen before selecting the game
+in the injector. The default Prestige menu key is Right Shift, which may overlap with a launcher keybind.
+
+For Lunar, the native log should identify `GenesisClassLoader`. Check the game log for `hooks installed`
+and `client initialised`. Hook counts refer to classes with changed bytecode. A skipped or failed hook
+can leave its feature unavailable even if the menu opens.
+
+An offline JVM replay accepted all 42 changed classes from Lunar's installed 1.21.11 cache after
+recalculating stack and local limits on the cached classes. Live injection and Dawn's in-game profile
+still need smoke testing.

 ## Install as a mod instead
 
 The payload jar is also a normal Fabric mod. Put `prestige-*.jar` (from `dist/` or the CI `payload-jar` artifact) in the
