chore(release): bump publishable packages to 0.0.52 (#712)

Ships #709 (TypeScript DX audit: JSDoc sweep, config-interface docs,
formal @example tags) and the public-surface hygiene removals (internal
ICON_*/CHAT_MARKDOWN_STYLES/surfaceToSpec/createClientToolsCoordinator
pruned from @threadplane/chat — 0 external consumers).

Atomic across all 7 publishable @threadplane/* packages; nx release publish
--dry-run green.
