Toolchain detection only knew fixed install locations (SDKMAN, nvm, pyenv…), so per-version managers were invisible and project-pinned versions were ignored; mise also only reaches PATH through an interactive-shell hook. JDK, Node.js, Python, Go and Maven installs under mise (MISE_DATA_DIR / XDG) and asdf (ASDF_DATA_DIR) are now detected, pinned versions from mise.toml variants and .tool-versions are resolved and used when the SDK setting is Automatic, and the managers' shims/installs are added to PATH when the login shell didn't.
Fixes#207

Language servers can be configured from settings.toml (global or project) and Settings › Language Servers: arguments, environment, initialization options and workspace settings per server, enable/disable, and any stdio LSP server can be added for a language. Settings-only changes are pushed with workspace/didChangeConfiguration; launch changes restart the server.
Also: re-enabling a server now detaches and stops the fallback that stood in for it, and a server added from the dialog is written as its own [languageServers.<name>] table.
