refactor(cli): move eleven local-only commands from sol to journal surface
Flip engage, journal-stats, indexer, top, health, streams, segment, providers, reprocess, restart-convey, and observer from access to service in the COMMANDS registry, and trim ACCESS_HELP_GROUPS to the surviving sol peer set.
Re-home production subprocess callers from the sol binary to journal for indexer, providers, and journal-stats call sites, including runner docstrings.
Sweep human- and agent-facing sol <cmd> references to journal <cmd> across docs, talent prompts, the health skill, Makefile, README, INSTALL, AGENTS.md, the stats dashboard, and .codex exec-policy rules, including a journal prefix allow rule.
Leave sol call health, sol call settings providers, and access stayers intact.
Broaden the migration test to scan .js and .rules, retarget positive expectations to stayers, and add a registry-derived guard that prevents production service commands from dispatching via sol.
Add one Unreleased changelog bullet with no version bump.
