QVAC-18580 chore[skiplog]: backmerge release-sdk-0.10.2 — version bump, changelog

[simon-iribarren]

Note: be concise and prefer bullet points.

🎯 What problem does this PR solve?

• Keeps main aligned with the v0.10.2 hotfix of @qvac/sdk shipping on release-sdk-0.10.2 (companion release PR: QVAC-18580 chore[skiplog]: release sdk 0.10.2 #1939).
• Without this backmerge, main would have a hole in its changelog history (no changelog/0.10.2/ folder, no v0.10.2 entry in the aggregated CHANGELOG.md) and package.json would still claim 0.10.1 even though @qvac/sdk@0.10.2 is on npm.

📝 How does it solve it?

• Cherry-picks (with -x) the single release-metadata commit a4f72257a from release-sdk-0.10.2 onto main.
• Carries only release metadata — no functional code. The delegation fix that ships in v0.10.2 (#1934) is already on main from its original merge (318f0c6a3).
• Files:
  • packages/sdk/package.json — 0.10.1 → 0.10.2 (single-line change, dependencies untouched)
  • packages/sdk/changelog/0.10.2/{CHANGELOG.md, CHANGELOG_LLM.md} — generated changelog files
  • packages/sdk/CHANGELOG.md — aggregated changelog (v0.10.2 added at top)

🧪 How was it tested?

This is a hand-crafted backmerge rather than a literal git merge release-sdk-0.10.2 → main because main has advanced past release-sdk-0.10.1 (the base of release-sdk-0.10.2) on multiple SDK dependencies. A literal merge would either bring up conflict markers or quietly regress these versions:

Dependency	release-sdk-0.10.1	main (current)
@qvac/diffusion-cpp	^0.3.0	^0.5.0
@qvac/embed-llamacpp	^0.14.0	^0.15.0
@qvac/llm-llamacpp	^0.17.1	^0.18.0
@qvac/transcription-whispercpp	^0.6.1	^0.6.5
hyperswarm	^4.12.1	^4.14.0
hyperdht	(absent)	^6.23.0
hyperblobs	(absent)	^2.8.0
peerDependencies block	(absent)	present

The cherry-pick of a4f72257a carries only the version-bump line in package.json (0.10.1 → 0.10.2) plus the new changelog/0.10.2/ folder and the root CHANGELOG.md aggregate update. Verified locally with git diff --stat upstream/main:

packages/sdk/CHANGELOG.md                      | 27 ++++++++++++++++++++++++++
packages/sdk/changelog/0.10.2/CHANGELOG.md     |  8 ++++++++
packages/sdk/changelog/0.10.2/CHANGELOG_LLM.md | 26 +++++++++++++++++++++++++
packages/sdk/package.json                      |  2 +-
4 files changed, 62 insertions(+), 1 deletion(-)

Same shape as the previous backmerge (#1910 for v0.10.1).
