Replopencode v1.18.32-repl32473.2 (PR #69)

Opt-in test build for REPL-32473, from PR #69.

Preserves saved unanswered questions across restarts and settles reply, dismissal, and Stop correctly. This revision simplifies the implementation by 47 production lines, adds negative coverage for stale/terminal question state, and removes 15 lines overall.

Validated with prompt, recovery, question lifecycle, and HTTP regression tests; package and monorepo typechecks; four binary builds; SDK generation; and repeated hard-restart HTTP smoke tests.

This is a prerelease for explicit installation only. It does not change the default stable release or deploy to the Replo fleet.
