Preserve verified session persistence while syncing remote runtime branch history

Origin/rcc/runtime advanced independently while this branch implemented
conversation history persistence. This merge keeps the tested local tree
as the source of truth for the user-requested feature while recording the
remote branch tip so future work can proceed from a shared history.

Constraint: Push required incorporating origin/rcc/runtime history without breaking the verified session-persistence implementation
Rejected: Force-push over origin/rcc/runtime | would discard remote branch history
Confidence: medium
Scope-risk: narrow
Reversibility: clean
Directive: Before the next broad CLI/runtime refactor, compare this branch against origin/rcc/runtime for any remote-only startup behavior worth porting deliberately
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: Remote-only runtime startup semantics not exercised by the session persistence change
