Function Signature Introspection With Visibility Metadata

via “elisp-function-signature-extraction-and-documentation”

** - elisp (Emacs Lisp) development support tools, running in Emacs.

Unique: Combines runtime introspection (via Emacs' function-documentation and help-function-arglist) with static AST parsing to handle both loaded and unloaded code, providing complete signature coverage

vs others: More complete than static-only analysis because it accesses live function objects with their actual arity and docstrings, and more reliable than pure runtime introspection because it falls back to parsing for unloaded code
