fix: real preset data for all VST2/VST3 plugins, template system with ground-truth registry

- Extracted preset data from all_plugins_v2.rpp for 14 previously broken plugins
- Fixed PLUGIN_REGISTRY entries: Kontakt 7, Gullfoss, ValhallaDelay, VC 160/76, The Glue
- Template parser falls back to PLUGIN_PRESETS when source RPP has fake data
- Substitute Transient Master (not installed) with FabFilter Pro-C 2
- All 25 plugins now load correctly in REAPER
- Added template generator scripts and ground truth references
- Cleaned up temp/debug files from output/

tests/test_reaper_builder.py
