plugin: ship Go/Python/TS language servers in the global plugin

[Tanq16]

Ships gopls, pyright-langserver, and typescript-language-server as part of the global plugin that configure and launch build, so Claude gets go-to-definition, find-references, workspace symbol search, and post-edit type diagnostics in every session by default — no -P needed, no build step.

Where it lives

writeGlobalLSP in internal/plugins/plugins.go lays a .lsp.json at the global-plugin root, mirroring writeGlobalManifest:

• Rewritten every build, not refresh-gated like skills/styles, so an added server or schema change reaches existing installs on the next launch without needing configure.
• All three shipped unconditionally, no toolchain detection. A server whose binary is absent is skipped by Claude Code and the rest still start, so gating on LookPath would only reimplement platform behavior — and worse, bake toolchain presence in at build time so a later go install/npm install wouldn't take effect until a rebuild.

The repo-root .lsp.json (which briefly shipped LSP via the claudex-dev plugin) is removed — keeping both would self-conflict on file extensions when this repo is loaded via -P alongside the global plugin, and Claude Code resolves that by silently dropping one.

Servers

Language	Binary	Install
Go	gopls	go install golang.org/x/tools/gopls@latest
Python	pyright-langserver	npm install -g pyright
TypeScript / JS	typescript-language-server	npm install -g typescript-language-server typescript@5

typescript is a second package — the server drives tsserver and ships without it. The @5 pin is load-bearing: typescript@latest is 7.x, which dropped the tsserver binary, and the language server fails initialize outright against it (verified: Could not find a valid TypeScript installation ... Exiting).

Verified

• .lsp.json schema checked against a claude plugin init --with lsp scaffold on 2.1.209
• Built the global plugin through the real BuildGlobalPlugin code path with the actual embedded FS; inspected the generated .lsp.json — valid, all three servers, correct extension maps
• Loaded that generated global dir headless: Loaded 3 LSP server(s) from plugin: claudex
• End-to-end against gopls earlier in this work: the LSP tool resolved a real symbol to its definition line, confirming the server starts and answers rather than the model guessing
• go build, go vet, gofmt, and go test ./... all pass; added tests assert the file is written with the three commands and is rewritten even on a no-refresh build

Notes

• --mcp none does not suppress language servers (LSP is not MCP); claude --bare is the escape hatch. README says so.
• Manifest description updated to name language servers alongside skills and output styles.
• [no ci] is in the title and commits. This is now Go code shipping to every session — if you want a release cut for it, drop [no ci] (and consider [minor-release]) at merge, since make version reads the merge-commit subject.
