Guardian REPL policy now sources from model metadata

Codex shifted Guardian REPL policy authority to reviewer model metadata, with a bundled fallback and safety checks on reuse.

Codex now sources Guardian REPL policy from the reviewer model's metadata [1], adding `auto_review.node_repl_policy` to model messages for `node_repl` and `cua_repl` reviews. The field falls back to the bundled policy when absent and skips injection when explicitly empty. Effective policy participates in Guardian session reuse checks, and unsafe parent-model fallback transitions that would change it are rejected. Additionally, Guardian user answers survive compaction [2]; recorded answers now match against retained review history, so compacted conversations still pass trusted answers to subsequent reviews. Explicit rollback still removes the associated answer. Two TUI fixes round out the day: agent navigation restores across reconnects [3] without losing selected tasks or drafts, and Left opens the agents overview from an empty, focused composer [4] in local-daemon sessions, leaving the configurable `open_agents` action unbound by default.
