27e8f56ad8 fix(audio): promote in-process VST3 to sandbox on editor-open (Windows crash) (#54)
Windows-only crash fix: opening an in-process VST3 editor faults via WndProc on the background message thread. OpenPluginEditor now promotes the slot to the out-of-process sandbox (state transferred via get/setStateInformation) via the new SignalChain::replaceProcessor, and opens the editor there.

Review hardening (multi-angle + Codex): state capture runs under the audio lock + SEH guard (SignalChain::captureVstStateForPromotion) so it can't race processBlock or fault the app; the transient sandbox pin is undone on promotion failure (isCrashedPlugin/removeCrashedPlugin) so a healthy plugin isn't stranded; replaceProcessor stages type/name/path for correct blocklist attribution; shared prepareForPlayback helper.

CI green incl. addon (windows-latest). Editor-open crash repro on a real Windows host still recommended as follow-up.
