v0.1.11

UX polish & stability

• Tool tooltips show both input and output on hover (streaming + history)
• Fix abbr title escaping (quotes replaced with apostrophes to survive markdown processing)
• Strip server_tool_use/advisor_tool_result blocks from stored history (fixes 400s on provider switch)
• Remove "Context compressed" inline chat notices (logged server-side instead)
• Image uploads include attachment ID text for LLM awareness
