v3.11.1

Bug Fixes

• @byline/admin — fixed a packaging regression that broke downstream production builds. The ./admin-activity subpath added in v3.11.0 (the system-activity ability module) was declared only in the top-level exports, but the package carries a publishConfig.exports block that npm uses to override exports at publish time — so the published v3.11.0 omitted the subpath. Any consumer importing @byline/admin/admin-activity (transitively, via @byline/host-tanstack-start) failed to build with "./admin-activity" is not exported. The subpath is now declared in both blocks, and an exports-parity guard test fails the build if they ever drift again. Workspace and dev builds were unaffected (they resolve through the top-level exports), which is why it surfaced only in a downstream production build.

All other @byline/* packages bumped to 3.11.1 in lockstep with no behavioural changes this cycle.
