Fix crash: Out-of-process plugin validation — test plugin in subprocess before loading in-process

Fix crash on load: Add try/catch around findAllTypesForFile + createPluginInstance, use async path

Fix: const auto& for file reference in showPluginMenu loop

Fix crash: Editor shows instant file-based popup menu — zero binary loading until select

Fix crash: Editor uses file listing, no scan — instant popup menu from filenames

Fix crash: Processor just lists files from disk — no scan, no binary loading

Fix crash: No plugin scanning — just list .vst3/.component files from disk, load on select

Fix crash: Update header — Timer-based scan, no background thread

Fix crash: Scan plugins on message thread via Timer (one per tick), not background thread"

Fix crash: Editor is thin — no threads, no scan ownership, just reads Processor state

Fix crash: Editor is now thin — just reads scan state from Processor, no threads

Fix crash: Processor owns scan thread + results, Editor just reads them

Fix crash: Move plugin scan into Processor (survives editor close), use safe async callback

Fix: Scan on button click in background thread, show menu when done — no more crash

Fix: Move plugin scan to background thread, scan on button click not on editor open

Fix: const auto& for temporary binding in loadPluginByIndex and showPluginMenu lambda
