Goal

Make EB Recorder install and load in OBS Studio 33+ using the official new third-party plugin layout, without touching working EB encoding or recording logic.

Changes

• CMake/ZIP now ship eb-recorder/eb-recorder.dll directly beside data/, not in bin/64bit/.
• The installer upgrades 0.3.2 installations using the existing atomic staging/rollback mechanism and validates the final flat DLL.
• Windows build-script package checks updated for the new layout.
• Portable OBS 33+ instructions and English/Russian documentation updated.
• Version bumped to 0.3.3 across CMake, application strings, locale files, and release notes.
• OBS 32.x users should remain on v0.3.2; OBS 33+ is the target for the new layout.
• The SDK build remains pinned to 32.2.2 for reproducibility; relevant EB APIs were unchanged in OBS 33.

Checklist before merging/release

• GitHub Actions Windows build passes; output ZIP and checksum verified
• eb-recorder.dll is present only in the root plugin folder of the ZIP
• Install on OBS 33 and upgrade from 0.3.2 without Legacy badge or duplicate plugin
• Verify six EB tracks + MKV recorder with Live/VOD audio and hotkeys on OBS 33
• Test clean uninstall

Draft intentionally: do not publish release until the user has validated v0.3.3. No CrossGPU changes are part of this PR.
