Shipped community-designed error handling for MCP server; TS frontend analysis achieves 96.6% route matching

The author released updates to the open-source project slnmap, implementing community-suggested error handling for MCP servers: wrapping failures as normal results with a machine-checkable status field and providing valid parameter lists. This fixed issues where clients couldn't see specific causes for tool-call errors and patched a bug leaking file paths. Additionally, a Watch mode was introduced, and a feasibility experiment for TypeScript frontend analysis showed that the TS Compiler API deterministically matched backend routes for 96.6% of 675 call sites in a 2,570-file React repo, also catching a live bug pointing to a non-existent endpoint. The goal is a unified graph from Chandlers to React components.
