Two heavy CLI tests were dominating wall time:
- chat.test.ts "--once exits with timeout note" waited the real 30s
reply-timeout floor. Added a replyTimeoutMs option to
runChatInteractive so the test can use 200ms.
- bundled-plugin-install.test.ts "loads the real bundled dependency
graph plugin" runs esbuild and a live PluginLoader (~18s). Gated
behind FUSION_RUN_SLOW_TESTS=1; the install/upgrade logic is covered
by mocked unit tests in the same file.
