Previous README used "방법 A/B/C" terminology that confused readers and
recommended Prism over the official launcher. Per user feedback, restructured
into a step-by-step guide assuming the official Mojang launcher:
1. boot 26.1.2 vanilla once to create .minecraft
2. run fabric-installer-1.x for client / 26.1.2 / loader 0.19.2
3. open .minecraft/mods (per-OS instructions)
4. drop fabric-api + video_player-0.4.1.jar, remove old versions
5. install JavaCV — two routes:
5-A. Prism Launcher (easiest)
5-B. official launcher via -Xbootclasspath/a: with Windows/macOS/Linux examples
6. verify with /videostick
Moved Maven coords to a developer footnote. Added install verification step
to disambiguate "missing texture" symptom from leftover old-version jars.
