fix[notask]: bump whisper-cpp from 1.7.5.1 to 1.7.6 to address CVE-2025-14569

[sharmaraju352]

Summary

• Bump whisper-cpp vcpkg dependency from 1.7.5.1 to 1.7.6 (latest available in the private registry)
• Adapt WhisperHandlers.cpp for API change: whisper_full_params.seed was removed in 1.7.6

Problem

CVE-2025-14569 documents a use-after-free vulnerability in whisper.cpp's read_audio_data function (CVSS 4.8). While the vulnerability is in CLI example code (not the libwhisper library we link), staying on an outdated version misses general stability and security fixes.

Solution

vcpkg.json:

- "version": "1.7.5.1"
+ "version": "1.7.6"

WhisperHandlers.cpp: The seed field was removed from whisper_full_params in 1.7.6. Updated the handler to a no-op:

{"seed",
 []([[maybe_unused]] whisper_full_params& params,
    [[maybe_unused]] const JSValueVariant& value) {
   // whisper_full_params.seed was removed in whisper.cpp >= 1.7.6
 }},

Note on Issue #7 (ONNX Runtime OOB read): The private vcpkg registry currently only has onnxruntime 1.21.0. The fix requires > 1.23.2 — this needs a registry-level port update and is tracked separately.

How was it tested?

• Full rebuild: Clean bare-make generate && bare-make build && bare-make install with 1.7.6 — compiles and links successfully (OpenMP dependency resolved via libomp)
• Unit tests (before & after): 24/24 pass, 90/90 assertions
• SDK integration (before & after): whispercpp-filesystem.ts produces identical transcription output (Alice in Wonderland passage)

This is not correct as seed is not present in any upstream whisper version but instead in our fork

[GustavoA1604]

The correct way to bump version in whisper is by updating qvac-ext-lib-whisper.cpp as we discussed in call. I think we can close this PR for now and bump the whisper version directly to 1.8.* according to the pitch

I do not think we can silently turn into a no-op. Existing tests and callers already pass under , so this changes reproducibility behavior without any API migration. I would either map that user-facing field onto the still-supported internal seed path, or reject it explicitly and update the docs/tests/callers in the same PR.

[ogad-tether]

Clarifying my review summary: the user-facing field I am concerned about is whisperConfig.seed. Existing tests and callers already set seed there, so turning that path into a silent no-op would be a behavior regression unless the field is remapped or rejected explicitly.

[ogad-tether]

whisperConfig.seed becomes a silent no-op, which looks like a behavior regression because existing callers/tests already use that field.
