git mv the 12 packages from session-persistence/, session-projection/, session-title/, and telemetry/ into one session/ group per the regrouping RFC; merge the four group READMEs into one bilingual triplet; rewrite the group segment in tsconfig references (intra-group references shorten to ../<pkg>), tsconfig.base.json paths/globs, knip.json keys, vitest include, gate scripts, and authored doc/note citations; regenerate module graph, doc graphs, catalogs, and the lockfile importer keys. No npm names change. Full unit suite: 8779 passed; the 18 reported failures reproduce as env flakes (ambient-proxy IPv6 tunneling, watched-dir inotify timeouts under parallel load) — each passes in isolation with NO_PROXY set, matching their known pre-existing behavior on master.
