fix(tsc): Phase 3d — fix 40 type errors across 15 files (87→47)

- contextCollapse stub: add 5 method stubs
- which.ts: utf-8 → utf8
- convertTools.test.ts, WebSearchTool, SkillTool, AttachmentMessage
- UserTextMessage dynamic require → React.createElement
- openai: AgentId cast, fetchOverride, streaming params
- constants: remove duplicate SYNTHETIC_OUTPUT_TOOL_NAME
