- src/lsp/index.ts is the explicit ./lsp package entry, yet held 2821 lines of
warmup, config caching, diagnostics, external build-command workspace
diagnostics, the writethrough batching subsystem and the LspTool class.
- Those are now servers, diagnostics, workspace-diagnostics, writethrough and
tool modules; index.ts is 22 lines and re-exports the same public surface.
- configCache and writethroughBatches remain single instances and every tuned
diagnostics timing constant moved verbatim.
