chore[notask]: release sdk + bare-sdk 0.13.2 — per-engine TTS language validation, drop bare-sdk node-only deps, rag 0.6.4

[opaninakuffo]

🎯 What problem does this PR solve?

• Cuts @qvac/sdk + @qvac/bare-sdk 0.13.2 on the release-sdk-0.13.2 line.
• Lands two already-merged main PRs that the release branch was missing (cherry-picked):
  • QVAC-20550 feat[api]: separate TTS language validation per engine #2581 — per-engine TTS language validation ([api])
  • QVAC-20720 chore: drop bare-runtime and bare-pack from bare-sdk deps #2585 — drop bare-runtime/bare-pack from @qvac/bare-sdk deps
• Updates bundled @qvac/rag to 0.6.4.

📝 How does it solve it?

• git cherry-pick -x of QVAC-20550 feat[api]: separate TTS language validation per engine #2581 (962607d) and QVAC-20720 chore: drop bare-runtime and bare-pack from bare-sdk deps #2585 (1b4e699).
• Bump sdk + bare-sdk 0.13.1 → 0.13.2; @qvac/rag ^0.6.2 → ^0.6.4 (mirrored into bare-sdk via qv-sdk-bare-sdk-sync).
• Align qv-sdk-bare-sdk-sync's SDK_ONLY_PACKAGES with check-deps-vs-sdk.mjs (bare-runtime, bare-pack). QVAC-20720 chore: drop bare-runtime and bare-pack from bare-sdk deps #2585 added them to the check script but not the sync script, so the sync was re-adding the deps QVAC-20720 chore: drop bare-runtime and bare-pack from bare-sdk deps #2585 just dropped.
• Generate the 0.13.2 changelog (CHANGELOG.md, CHANGELOG_LLM.md, api.md, root aggregate).

🧪 How was it tested?

• Confirmed QVAC-20550 feat[api]: separate TTS language validation per engine #2581/QVAC-20720 chore: drop bare-runtime and bare-pack from bare-sdk deps #2585 were absent from release-sdk-0.13.2 before cherry-picking (TTS_CHATTERBOX_LANGUAGES not present; bare-sdk still declared bare-runtime/bare-pack).
• cd packages/bare-sdk && bun run check:deps-vs-sdk → OK (dependencies=26).
• TTS schema unit tests ship with QVAC-20550 feat[api]: separate TTS language validation per engine #2581.
