Use public_send instead of send for public methods

[AbishekRaj2007]

formula.send(:stable)/formula.send(:head), formula.deps.send(type), and SimulateSystem.send(...) were all calling methods that are already public, so there was no real need for send's private-method backdoor.

Switching these to public_send makes that clear to readers and keeps Ruby's normal privacy checks in place if any of these methods are ever made private.

No behaviour change: every target method was confirmed public before switching, and
./bin/brew typecheck/style/tests all pass.

Disclosure : This changes were suggested by Claude Sonnet 5 and fixed by myself, I have edited and reviewed all the changes.
