* feat(daemon): add minimum Claude Code version check during runtime registration
The daemon now validates the detected agent CLI version against a
minimum requirement before registering a runtime. Claude Code requires
>= 2.0.0 (when --output-format stream-json and --permission-mode
bypassPermissions were introduced). Older versions are skipped with a
warning log, preventing silent failures.
Closes#569
* feat(daemon): add minimum Codex CLI version check (>= 0.100.0)
The `codex app-server --listen stdio://` flag was introduced in v0.100.0.
Older versions lack this flag and fail silently. Add codex to the
MinVersions map so the daemon skips outdated codex CLIs with a clear
warning, matching the existing Claude version check.
