Ruben Fiszel a46aa641f9 feat: add R language support (#8263)
* feat: add R language support

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.

* feat: add R package resolution and installation

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

* feat: add nsjail sandboxing for R resolve and install phases

* fix: fix R get_variable/get_resource and add sandbox annotation + e2e tests

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: fix R arg inference with JS fallback parser and get_variable/get_resource

* fix flake

* nsjail

* nits

* fix: R install improvements - suppress verbose output, flat lockfile logging, Dockerfile R support, rlimits

- Suppress renv verbose output during resolve and install (controlled by #verbose annotation)
- Filter renv from install list (already loaded, causes noisy restart message)
- Log compact "resolved N packages" instead of full renv.lock JSON
- Add R (r-base, r-cran-renv) to DockerfileFull and DockerfileFullEe
- Use disable_rl for nsjail install config (R compiles from source)
- Reduce default concurrency from 20 to 5
- Add rlang to openflow.openapi.yaml
- Fix MainArgSignature (no_main_func -> auto_kind) after main merge
