feat(chat): MCP tool apps — custom inline renderers for 12 tools

12 of 33 MCP tools now render as rich inline cards instead of raw JSON:
EntityCard, HealthSummary, LXCList, EntityTable, KnowledgeResults,
BlastRadius, ChangeLog, FleetSnapshot, MetricChart.

Architecture:
- Server: annotateJSONResult() wraps queryRows with __renderer hints
- Registry: match/dispatch system maps tool names to Svelte components
- Chat: inline dispatch with 5-card limit, overflow to collapsed group
- ToolCallGroup: unmatched prop, hides when all matched, ARIA labels

Tests: 3 new Go tests for annotateJSONResult (wrap, no-op, multi-row).
