Every MCP tool call triggered a full filesystem scan and held a write lock for the entire duration. For large solutions this added seconds of latency to every tool invocation. - Add tiered cooldowns: 5s for document timestamps, 60s for directory scans - Move stat collection outside the write lock so concurrent tool calls are not blocked while checking for changes - Cache file paths and project IDs in DocumentInfo record to eliminate Roslyn GetDocument() lookups in the refresh hot path - Remove redundant File.Exists calls (GetLastWriteTimeUtc returns a sentinel for missing files) - Pre-compute bin/obj path prefixes to avoid per-file string allocation - Simplify RefreshChangedDocumentsAsync to return Task (result was unused) - Bump to 0.6.3
