增加了空回为失败和自定义失败关键词的功能，修复了机器人提出的问题 (#153)

* Add proxy failure rules for keywords and empty responses

* fix(proxy): detect failure keywords for streamed chat responses

* Fix(tester): treat empty stream output as error

* feat(server): default listen host to IPv6 any-address

* fix(proxy): treat empty upstream content as failure

* Revert "feat(server): default listen host to IPv6 any-address"

This reverts commit 2ca49a3891cc3a2e37138156b17b660b6a3cb7ea.

* fix(settings): validate proxy failure settings

* fix: address CodeRabbit feedback in proxy failure detection

* test: force NODE_ENV=test for vitest to avoid React act() prod build

* fix(proxy/chat): preserve true SSE streaming (no upstream.text buffering)

* fix: avoid http fallback after hijacked SSE stream

* fix: wire proxy failure detection into chat and responses
