Implements the LSP capability seam RFC as three packages: dsh-lsp (the ctx.lsp interface — provider registry by branded id + exclusive extension mapping, per-query order-independent selection, closed request/result vocabulary, LspError taxonomy), dsh-lsp-local (a generic stdio language-server provider — Content-Length JSON-RPC framing, per-(provider, workspace) process single-flight, transient didOpen/query/didClose, an abortable per-instance queue, UTF-16 negotiation, host-namespace source reads outside ctx.fs, and bounded shutdown/kill teardown), and dsh-tool-lsp (the model-facing lsp tool — four operations, one-based UTF-16 cursor conversion, workspace-grouped location rendering, hover capping, a required session workspace, and a timeout budget). Why: an agent had text search and file reads but no way to identify a program symbol — follow an alias, connect an interface to implementations, or read an inferred type — before changing code. Splitting model contract, seam, and local subprocess behavior keeps the four semantic queries stable across future remote or sandbox-native providers without leaking a JSON-RPC escape hatch.
