QVAC-19908 chore: release sdk + bare-sdk 0.13.4 — recover Qwen hybrid tool-call frames

[simon-iribarren]

🎯 What problem does this PR solve?

Publishes @qvac/sdk + @qvac/bare-sdk 0.13.4, a fix-only patch release.
It recovers malformed Qwen hybrid tool-call frames (#2677), which downstream
agentic consumers (the opencode-plugin / ai-sdk-provider path) are waiting on.

This release is intentionally scoped to only the tool-call fix: the branch is
based on the previous release point (sdk-v0.13.3) with #2677 cherry-picked on
top, so other work already merged to main (e.g. subscribeServerLogs, input
validation errors, TTS test changes) is not included here and will ship in a
later release.

📝 How does it solve it?

• Branch cut from sdk-v0.13.3 + cherry-pick of QVAC-19908 fix: recover Qwen hybrid tool-call frames #2677 (-x), so the published
  tree is 0.13.3 plus only the parser fix.
• Bumps the version field in packages/sdk/package.json and
  packages/bare-sdk/package.json from 0.13.3 → 0.13.4 (lockstep).
• Adds packages/sdk/changelog/0.13.4/ (CHANGELOG.md, CHANGELOG_LLM.md) and
  prepends the aggregated 0.13.4 entry to packages/sdk/CHANGELOG.md.
• No dependency ranges changed, so NOTICE files are unchanged and were not
  regenerated.
• Merging into release-sdk-0.13.4 triggers the GPR publish; the npm publish
  follows once the companion backmerge PR lands on main.

🧪 How was it tested?

• Changelog generated with node scripts/sdk/generate-changelog-sdk-pod.cjs --package=sdk (base tag sdk-v0.13.3); it resolves to exactly one PR (QVAC-19908 fix: recover Qwen hybrid tool-call frames #2677).
• bare-sdk lockstep verified via the sync script (version-only change).
• The fix itself already passed CI on main as PR QVAC-19908 fix: recover Qwen hybrid tool-call frames #2677.
