fix(mitm): Kiro binary EventStream crash + add models & TTS tool filtering

- server.js: isBinaryData() skips binary AWS EventStream bodies (fix JSON parse crash)
- kiro.js: isBinaryEventStream detection + migrate to pipeTransformedEventStream pipeline
- base.js: add pipeTransformedSSE / pipeTransformedEventStream helpers
- chatCore.js: filter tool messages + tools for TTS models via getModelType()
- providerModels.js: add getModelType()
- cliTools.js: add gpt-5-mini (Copilot), glm-5 & minimax-m2.5 (Kiro)
