chore: bump version to v0.25.9v0.25.9

Code quality fixes from audit:
- Log silently discarded errors in status sinks and stats.Update call sites
- Fix json.Marshal errors silently ignored in LSP handlers
- Replace time.Sleep in tests with channel signaling (mcp) and fake clock (stats)
- Make context cancellation work in production time.Sleep sites (handlers_document, cmdentry)
- Remove init()-based provider registration from llm package; use explicit RegisterAllProviders()
- Add WaitGroup goroutine tracking to MCP server Run()
