l0ng-ai 2cd16a723d fix(lsp): let language servers register the files they watch (#1223)
* fix(lsp): resolve newly installed Python packages without a restart

Packages installed into an excluded .venv (uv add, uv pip install) never
reached the Python language servers: the watcher reports changes in excluded
folders only as excluded_dirs, and didChangeWatchedFiles forwarded nothing but
the server's own source files. basedpyright kept its failed import resolution
until restarted.

Language servers get a watched-files list of globs. Files matching it, and
excluded folders matching it, are forwarded too; the Python servers watch
their configuration and site-packages.

* fix(lsp): let servers register the files they watch

Clients now support dynamic registration of workspace/didChangeWatchedFiles,
with relative patterns. Changes on disk go to each server as its registered
watchers match them, including folders in excluded trees (a package installed
into .venv, go.mod rewritten by go get). Folders outside the project that
relative patterns name (a virtualenv elsewhere, a path dependency) get their
own watchers. Servers that register nothing keep hearing of their languages'
files.

Registrations sent right after initialized are no longer dropped while the
server is still being marked ready.

Replaces the per-server watched-files list.

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.

Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.

A release build of OpenIDEA from main and IDEA with default settings and plugins, on Windows 11, 32-core AMD, 62 GB RAM. IDEA analyses Python more deeply, so "ready" doesn't mean the same work on both sides. Both are measured from the outside, the same way: see perf/compare to run it on your machine and projects.
