[BCI] QVAC-17072 chore: prepare for registry-based whisper-cpp consumption

[sharmaraju352]

Summary

• Once [BCI] QVAC-17071 feat: add BCI patches to whisper-cpp port qvac-registry-vcpkg#122 merges, update vcpkg-configuration.json baseline to the merged commit
• Remove the local vcpkg-overlays/whisper-cpp/ directory (registry now provides BCI-patched whisper-cpp)
• Remove the whisper-cpp version override from vcpkg.json

Stacked PR

This is PR 3 of 6 in the BCI addon stack (based on PR 2: #1584):

1. QVAC-17057 - POC with batch transcription ([BCI] QVAC-17057 feat: add bci-whispercpp POC with batch transcription #1583)
2. QVAC-17071 - Update qvac-ext-lib-whisper.cpp ([BCI] QVAC-17071 chore: switch whisper-cpp overlay to tetherto fork #1584)
3. QVAC-17072 - Update qvac-registry-vcpkg with updated whisper.cpp (this PR)
4. QVAC-17062 - Add streaming capabilities and integration tests ([BCI] QVAC-17062 feat: add streaming transcription and integration tests #1586)
5. QVAC-17058 - Add empty BCI workflows to main ([BCI] QVAC-17058 ci: add empty BCI workflows to enable branch triggering #1587)
6. QVAC-17063 - Add full CI workflows for all platforms ([BCI] QVAC-17063 ci: add full CI workflows for prebuilds, desktop and mobile tests #1588)

Dependencies

• Registry PR: [BCI] QVAC-17071 feat: add BCI patches to whisper-cpp port qvac-registry-vcpkg#122 must merge first
• This PR will be updated with actual baseline hash and overlay removal once registry is updated

Test plan

• Update vcpkg-configuration.json baseline to registry commit hash
• npm run build succeeds with whisper-cpp from registry (no local overlay)
• npm run test:integration passes

Closing — this PR was a placeholder that is now superseded.

The BCI whisper.cpp changes are handled via:

• External lib: tetherto/qvac-ext-lib-whisper.cpp#10
• Local overlay patches are already included in PR [BCI] QVAC-17057 feat: add bci-whispercpp POC with batch transcription #1583 (the POC PR)

The 6-PR stack has been collapsed to 4 PRs. PRs #1584 and #1585 (whisper-lib switch + registry consumption) were net-zero (commit + revert) and are no longer needed.

New stack:

1. [BCI] QVAC-17057 feat: add bci-whispercpp POC with batch transcription #1583 — POC with batch transcription (includes all review fixes)
2. [BCI] QVAC-17062 feat: add streaming transcription and integration tests #1586 — Streaming transcription
3. [BCI] QVAC-17058 ci: add empty BCI workflows to enable branch triggering #1587 — Empty CI workflows
4. [BCI] QVAC-17063 ci: add full CI workflows for prebuilds, desktop and mobile tests #1588 — Full CI workflows
