Add R as a new supported scripting language in Windmill, following the same pattern used for Ruby. Includes: - Backend: ScriptLang::Rlang enum variant, DB migration, tree-sitter-r parser crate with tests, WASM parser binding, R executor with NSJail sandboxing, job dispatch and signature parsing - Frontend: language picker, R icon, syntax highlighting, editor bar insertions (Sys.getenv, get_variable, get_resource), schema inference, init code template, BETA badge - CLI: .r extension mapping, sync support, bootstrap template R scripts use `main <- function(...)` syntax, jsonlite for JSON serialization, and system curl for the Windmill client helper.

Parse library()/require() calls from R scripts to extract dependencies. Resolve versions from CRAN, cache lockfiles in pip_resolution_cache, and install packages to a shared R library cache. The run step sets R_LIBS_USER so installed packages are available to the script. - Parser: parse_r_requirements() extracts package names from AST - Executor: resolve() generates lockfile, install() installs from CRAN - Worker lockfiles: wire up R resolve for dependency jobs Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Add R as a new supported scripting language in Windmill, following the Ruby executor pattern. Users can write R scripts with
main()functions, uselibrary()/require()for dependencies (auto-detected and installed from CRAN), and access Windmill variables/resources via built-in helpers.Changes
