Adds a `jaclang-extension.syntaxHighlightingOnly` boolean setting (default false). When enabled, the extension skips EnvManager initialization and LSP startup, and the Jac-specific menu/context commands (run, debug, restart language server, serve, lintfix) are hidden via `when` clauses. Useful for environments where users only need syntax highlighting and do not have a Jac runtime installed.
