…ch output - Add `leann_build` tool: build/update indexes directly from MCP, supports incremental updates so the index stays current as code changes - Add `leann_status` tool: show index details (backend, embedding model, chunk count, file count, size) - Switch `leann_search` to use --json output with file paths always included, formatted as markdown code blocks for better code context - Fix float32 JSON serialization in `leann search --json` - Clean up tool descriptions to be concise and action-oriented - Bump MCP server version to 2.0.0 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Platform-aware default embedding model (bge-base-en-v1.5 on NVIDIA GPU, all-MiniLM-L6-v2 elsewhere). Normalize model names to prevent false mismatch on incremental updates. MCP build auto-inherits embedding config from existing index. Fix full rebuild path to reload all documents. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Strengthen LEANN's incremental update story — from MCP integration to smart defaults to correctness fixes.
