* fix(core): add Sentry client-side tracking and fix postinstall append logic
Add SENTRY_CLIENT_KEY support to the SSR analytics wrapper so templates
can inject the Sentry browser SDK loader alongside GA. Add the loader
directly to the docs site.
Fix scaffoldRequiredPackages to append build commands to an existing
postinstall script instead of skipping — previously, add-app into a
workspace with an existing postinstall (Husky, codegen) would silently
skip the required package builds.
* chore(core): bump version to 0.7.12
