QVAC-18417 tts-ggml: bump tts-cpp to 2026-06-03 (23 multilingual languages, #19)

[freddy311082]

What

Bumps the tts-cpp dependency to 2026-06-03 (TTS GGML support for all 23
multilingual languages — qvac-ext-lib-whisper.cpp PR #19, merged to master as
c1fd35d8) and moves the vcpkg registry baseline to the qvac-registry-vcpkg
commit that serves that version.

Changes

• packages/tts-ggml/vcpkg-configuration.json: registry baseline 74d2dfd0 → 9eb53a42.
• packages/tts-ggml/vcpkg.json: tts-cpp version>= 2026-06-02#1 → 2026-06-03.

Test plan

• CI green: tts-ggml resolves and builds tts-cpp@2026-06-03.

The diff itself is correct and minimal, but CI is fully red and the PR should not merge as-is — every build/test/lint job fails for a single upstream reason (details below). Leaving as a comment rather than approving.

The diff is valid

• New registry baseline 9eb53a42 does serve tts-cpp@2026-06-03 (verified in qvac-registry-vcpkg versions DB: 2026-06-03#0), so the baseline move and the version>= bump are internally consistent.

Blocker: the tts-cpp@2026-06-03 registry port has a bad source SHA512

All 9 prebuild jobs (linux/android/ios/darwin/win), cpp-tests-coverage, and cpp-lint fail at the same step — downloading the tts-cpp source archive:

error: building tts-cpp:<triplet> failed with: BUILD_FAILED

The SHA512 recorded in the tts-cpp@2026-06-03 portfile (5220e542…) doesn't match the tarball GitHub actually serves for commit c1fd35d8 (67306c98…). It's deterministic across every runner and platform, so it's not a transient download glitch — the recorded hash is simply wrong for that commit's archive.

This is not fixable in this PR — the source-bump diff is right; the broken port lives in qvac-registry-vcpkg. Next steps:

1. Fix the tts-cpp@2026-06-03 portfile's SHA512 in qvac-registry-vcpkg (re-record the correct hash for c1fd35d8, after confirming the archive content is the intended merge commit), publish a new registry commit.
2. Repoint this PR's vcpkg-configuration.json baseline at that new registry commit and re-run CI.
3. Don't merge until at least the prebuild + cpp-tests matrix is green — the test-plan checkbox ("CI green: resolves and builds tts-cpp@2026-06-03") is currently failing.

(merge-guard / validate-pr is just the verified-label gate — ignore.)
