v0.6.0

What's Changed

Bug Fixes

• Fix vault appearing empty via MCP — normalize QMD file field to path and strip qmd:// prefix
• Fix compile-flag bug — sources with failed LLM enrichment are no longer stuck; enrichment_status frontmatter tracks whether enrichment actually succeeded
• Fix blocking I/O in async paths — offload log_operation file writes and build_context_window note reads to threads
• Fix duplicate MCP service initialization — REST and MCP now share the same graph/QMD/compiler instances
• Fix get_edges_batch overhead — replace unnecessary asyncio.gather with direct loop for in-memory operations

New Features

• vault_compile(force, path) — recompile specific sources or force re-enrichment of stuck notes
• Search caching for stdio MCP — repeated queries served from 30s TTL cache
• Async vault scan in MCP fallback — prevents event-loop blocking during standalone MCP startup

Tests & Benchmarks

• 8 performance benchmarks covering search, context building, MCP startup, and cache hits
• 254 total tests passing
