- Add complete call-seq documentation for 4 missing public methods:
* Proc#lambda?: returns true if proc is a lambda, false if regular proc
* Proc#source_location: returns [filename, line] or nil for native procs
* Proc#to_s/inspect: returns string representation with location info
* Kernel#proc: equivalent to Proc.new, creates proc from block
- Add helpful comment for internal mrb_proc_source_location helper function
- Improve TODO comment clarity for cfunc aspec limitation
- Achieves 100% public API documentation coverage (5/5 methods documented)
- Improves code maintainability and follows mruby documentation standards
