The search function is not working.

[Prodesire]

Pressing Ctrl+R enters search, but the search function does not actually work.

Fixed in PR #62. Ctrl+R history search now opens reliably in the REPL and searches prompts from persisted input history plus the active agent context, so selected history is inserted back into the input buffer instead of being submitted accidentally.

PR: #62

Verified with make translate, make format, make lint, and make test (3777 passed, 244 warnings).

Closing as completed.
