chore(release): 0.9.67 - ClickHouse and Apache Druid

[cevheri]

Version bump for the 0.9.67 release. Two new engines shipped since 0.9.66 (ClickHouse #270, Apache Druid #271) but neither has been in a release yet, which left README, BRAND_MESSAGING and the SUSE catalog copy claiming ten engines against a released product that has eight. This closes that gap.

Bump contents

• package.json 0.9.66 -> 0.9.67
• bun run chart:bump: chart 0.1.28 -> 0.1.29, appVersion 0.9.67, image tag, chart README, operator chart copy
• artifacthub.io/changes rewritten by hand for 0.1.29 (chart:bump does not touch it), then chart:bump re-run so the operator chart copy carries the new annotation
• make -C operator bundle: CSV libredb-studio-operator.v0.9.67 and controller image tag

No chart template changes — the rendered manifests are identical to 0.1.28.
