Extracts functions, S4 classes, R6 classes and RefClass (`setRefClass`) classes with their methods and fields, and resolves `library()` / `require()` / `source()` imports to local packages and files, `obj$method()` and `pkg::fn()` calls, R6 `inherit=` / S4 `contains=` heritage and NAMESPACE-driven export status.

With `--pdg` it also builds a control-flow graph (control dependence only; R has no reaching definitions), and `rename` handles plain functions while refusing classes, members, S3 methods, exported package functions and names spelled as strings.

-**Control flow (CFG, opt-in `--pdg`)** — provider-owned control-flow graphs (`BasicBlock` nodes + `CFG` edges) feed control dependence and reaching definitions across the registered source languages. AST providers describe callable regions; COBOL uses source-backed program regions. Unsupported constructs and region limits produce explicit skips. Off by default.
